Solve system of equations.
1/3x-3 y=-4
x-9 y=-12
The system of equations involving 1/3x - 3y = -4 and x - 9y = -12 has infinite number of solutions.
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
1/3x - 3y = -4 (equation 1)
x - 9y = -12 (equation 2)
Using the second equation, find the value of one variable, lets say x, in terms of the other.
x - 9y = -12 (equation 2)
x = 9y - 12
Substitute the equation of x to the first equation.
1/3x - 3y = -4 (equation 1)
1/3(9y - 12) -3y = -4
3y - 4 - 3y = -4
Combining the all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.
3y - 3y = -4 + 4
0 = 0
Since we did not get unique values for x and y, check if one of the equations is a simplified form of the other. Multiply the first equation with 3.
1/3x - 3y = -4 (equation 1)
3(1/3x - 3y) = 3(-4)
x - 9y = -12
Since this new equation is the same with the second equation, this means that the lines of the two equations are the same(overlapping). Hence, the system of equations has infinite number of solutions.

The length of the rectangle given below is more than the width of the rectangle. Write the inequality you would use to solve the problem. Then, Solve the inequality. Make sure you use the proper notation for your equation and answer.
Answer:
Inequality:
8in > x - 5in
Solution:
x < 13in
Step-by-step explanation:
If the length 8in is is bigger than the width (x - 5in) then we just need to write it:
8in > x - 5in
To solve for x, we need to move everything but x to the other side
8in > x - 5in
13in > x
what is the relationship between the values of the two 4s in the weight of the potatoes?
The relationship between the values of the two 4s in the weight of the potatoes is that the first number is 10 times the second 4.
How to illustrate the information?In this case, the weight of a potato is given as 3.441g.
It should be noted that the first 4 is in the tenth place and is written as 0.4.
On the other hand, the second 4 is in the hundredth place. The value is 0.04.
Therefore, the relationship between the numbers will be:
= 1/10 × 1/10 = 1/100
Therefore, the relationship between the values of the two 4s in the weight of the potatoes is that the first number is 10 times the second 4.

a person starts walking from home and walks: 3 miles east 7 miles southeast 4 miles south 5 miles southwest 4 miles east
Distance can be defined as the amount of ground covered or walked by a physical object, regardless of its direction, starting or ending point.
How to calculate the total distance?In order to determine the total distance walked by this person, we would simply add each of the distances recorded together as follows:
Total distance = 3 + 7 + 4 + 5 + 4
Total distance = 23 miles.
How to determine the total displacement vector?In order to determine the total displacement vector, we would add all of the vectors together as follows:
3 miles East = <5, 0>
7 miles Southeast = <7/√2, -7/√2> or <7cos45°, -7sin45°>
4 miles South = <0, -4>
5 miles Southwest = <-5/√2, -5/√2> or <-5cos45°, -5sin45°>
4 miles East = <4, 0>
Total displacement vector = <5 + 7/√2 + 0 - 5/√2 + 4, 0 - 7/√2 - 4 - 5/√2 + 0>
Total displacement vector = <9 + 2/√2, -4 - 12/√2>
Total displacement vector = <9 + 1.41, -4 - 8.49>
Total displacement vector = 10.41i - 12.49.
If this person walked straight home, the total distance walked is giving by the resultant of the above displacement vector:
Total distance = √[10.41² + (-12.49)²]
Total distance = √[108.37 + 156.00]
Total distance = √264.37
Total distance = 16.26 miles.

Brittany says she can read about 220 words per minute. She has a book that is 300 pages long and each page has about 370 words per page. How many hours will it take Brittany to finish the book?
We want to do a change of units of a rate, from words per minute to words per hour.
We will find that the answer is 22,200 words per hour.
The rate that we need to modify is:
370 words/minute
So the time is in the denominator.
Also, remember that:
1 hour = 60 minutes.
Then:
1 minute = (1/60) hours.
Using the above relation, we can replace the "minute" in the denominator by (1/60) hours, so we get:
370 words/minute = 370 words/((1/60) hours.) = 60*370 words/hour
22,200 words/hour.
Then the rate is 22,200 words per hour.

Step-by-step explanation:
Although they seem to remain unchanged, many mountains undergo steady
growth. If erosion and weathering are ignored, some mountains, like the San
Gabriels in southern California, grow as much as 1.0 cm within a year. If a
year is considered to be exactly 365 days, what is the speed at which the San
Gabriel Mountains grow in kilometers per hour?
Using proportions, the San Gabriel Mountains grow 0.00000000114 km/h.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, we have that:
Each cm has 0.00001 km.Each day has 24 hours, hence a year has 365 x 24 = 8760 hours.Hence the speed is:
0.00001/8760 = 0.00000000114 km/h.

Your question was incomplete. Please refer the content below:
If 6 bales are needed to feed 40 head of cattle, how many bales are needed to feed 50 head of cattle?
By using unitary method, we get that 7.5 bales are need to feed the 50 heads of cattle.
We are given that:
6 bales are need to feed the 40 heads of cattle.
We need to find out that how many bales will be needed to feed the 50 heads of cattle.
Here, we will be using the unitary method.
So, 40 heads need = 6 bales
1 head needs = 6/40 bales
1 head needs = 3 / 20 bales.
So, 50 heads will need:
50 heads will need = 3 / 20 × 50 bales
50 heads will need = 3 / 2 × 5 bales
50 heads will need = 7.5 bales.
Therefore, by using unitary method, we get that 7.5 bales are need to feed the 50 heads of cattle.

the first possession of each nfl game is decided by a coin toss. is this process deterministic, or truly random?
A coin toss determines the first possession of each NFL game. This process deterministic not random event because the initial coin flip only determines whether a team receives the ball now at start of the first or third quarter.
What is meant by first possession?Possession in football refers to a team keeping possession of the ball for as longer as possible in order to create opportunities for goals and prevent this same opposition from posing a threat to the team's goal.
Some key features regarding the first possession in NFL game are-
The scoring team wins if the first possession results in such a touchdown (by receiving team or a defensive team on a turnover) or a safety by the defensive team. If the receiving team is unable to score and loses possession, this same game is decided by sudden death, with the first team to score winning.Many NFL fans oppose the current overtime setup in which the winning team can elect to catch the ball, move down the field, and score, effectively ending the game without allowing the opposing team to touch the ball on offense.If the resolution of player decisions results in completely predictable outcomes, the game is deterministic.

a traffic study has shown that the probability that 55 cars will pass over a small bridge in a 4-4-minute period is 0.16.0.16. what are the odds against exactly
Final answer:
The odds against exactly 5 cars passing over the bridge in that time is calculated as 4:21
Why don't we use probability instead of odds ?
A probability must be between 0 and 1 (nothing can happen with a greater than 100% likelihood). The chances are not as limited. Odds can be any positive number; for example, a chance of 2/3 is equivalent to odds of 2/1. By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula.
By dividing the odds in the first group by the odds in the second group, the odds ratio is calculated. For many clinicians, odds and odds ratios are difficult to comprehend. Odds are calculated by dividing the likelihood of an event happening by the probability that it won't.

When designing a rectangular patio, a landscaper places a coordinate grid on top of the design.
One side of the patio is represented by the line
y=2/3x+5/3
The other three sides of the patio will be represented by one line with a slope of (BLANK) and two lines with a slope of (BLANK).
The other three sides of the patio will be represented by one line with a slope of 2/3 and two lines with a slope of -3/2.
What is general equation of a Straight line?The general equation of a straight line is -
y = mx + c
Given in the question is a equation that describes the one side of a rectangular patio. From the question, we can write -
Equation representing a side of Patio - y = 2/3x + 5/3
If we compare the equation representing a side of Patio with the general equation of line, we get -
y = 2/3 x + 5/3
[y] = [m] x + [c]
From this we can conclude that -
m = 2/3 = slope of line
c = 5/3 = y - intercept
The patio is in the shape of a rectangle. Therefore, the side opposite to the line of slope → 2/3 will be equal in length and parallel to it. We know, that the slope of two parallel lines are same. So, the slope of line parallel to y = 2/3x + 5/3 will be 2/3.
The remaining two sides are perpendicular to both the side of slope → 2/3. The remaining sides are also parallel to each other, indicating they both have same slope. The slope of a line perpendicular to a given line (L) is given by -
m [p] x m [L] = -1
m [p] = - 1 / m [L]
m [p] = - 3/2
Therefore, the remaining two sides will have slope of -3/2.
Therefore, the other three sides of the patio will be represented by one line with a slope of 2/3 and two lines with a slope of -3/2.

According to the given statement Outliers would be any sightings that are more than 1.5 IQR below Q1 or more then 1.5 IQR above Q3.
What does the term "outlier" signify in statistics?An outlier is a value that is significantly different from the other values in a random sampling of a population. In some ways, this definition leaves it up towards the analyst (or a consensus process) to determine what is abnormal.
What is the significance of identifying outliers?Identifying potential outliers is critical for such following reasons. An outlier could imply faulty data. For example, the data could have been wrongly coded, or an experiment could have been done erroneously.
According to the given data:An outlier is defined as an observation that is less than or more than Q3 times IQR.
We need to look for place variances in Q1 and Q3.
When we utilize the IQR approach to discover outliers outside of Q1 and Q3, we create a "fence." Outliers are any values that fall outside of the defined boundary.
To construct this fence, we take 1.5 times the IQR, deduct it from Q1, and add it to Q3.
IQR = (1.5 - Q1)
IQR = (1.5 + Q3)
This provides us with the minimum and maximum fence posts to which we can compare every observation.

Subtraction in mathematics is the process of subtracting one number from another. This is a first-order arithmetic operation, represented by the subtraction sign (-), and is a method of calculating the difference between two numbers and the length of a segment. Subtraction is an operation which is used to find the difference between numbers. If you have a group of objects and remove some objects from it, the group will be smaller. For example, you bought 9 cupcakes for your birthday party and your friend ate 7 cupcakes. Now he has two cupcakes left. This can be written in the form of the subtraction formula 9 - 7 = 2, read as "9 minus 7 is equal to 2". If you subtract 7 from 9, (9 - 7) becomes 2.Solving the equation
