What is an equation in point slope form of the line that passes through (7, 1) and (-3,9)
Answers
Answer:
y= -4/5x+33/5
Step-by-step explanation:
for questions like these, the slope is always defined as the change in y over the change in x or use the equation m=y2-y1/x2-x1.
x1=7 and y1=1
x2=-3 and y2=9
now plug these numbers in to the equation. m= 9-1 / -3-7 Or m= 8/-10 simplified to m= -4/5
now that we have the slope you can plug it in to the equation y=mx+b and get y= -4/5 + b.
to find b, the y-intercept, you can use either of the two points and the answer will be the same. for this one, I'll use (7,1).
1= -4/5 x 7+b. b= 33/5

Steve is first in the ratio if the ratio of guitars is 4:3.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other. A set of data points can be used to observe the constant relationship. A set of data with a constant relationship between two values is a comparison of miles traveled to hours traveled. A special type of ratio is the comparison of two different quantities.
The general form of expressing a ratio between two quantities say 'a' and 'b' is a: b
Jenny has 3 guitars. Steve has 4 guitars.
The ratio is 4:3, which represents 4/3 or 4 parts Steve to 3 parts Jenny.
Hence, Steve is first in the ratio.

Isabella ran the 100-meter dash five times. The time it took her to complete each race, in seconds, was 12.7, 12.807, 12.78, 12.08, and 12.087.
Isabella wants to order the race times from her slowest time to her fastest time. Sort the decimals in order from greatest to least.
Answers
Given:
Number of 100-meter races = 5
The time it took Isabella to complete each race, in seconds, was 12.7, 12.807, 12.78, 12.08, and 12.087.
To find:
The decimals in order from greatest to least.
Solution:
The time it took Isabella to complete each race, in seconds, was shown below:
12.7, 12.807, 12.78, 12.08, 12.087
We need to arrange this data in descending order.
In all 5 numbers the digits before decimals are same. On comparing the digits on the tenth place and hundredth place, we get
12.807 > 12.78 > 12.7 > 12.087 > 12. 08
Therefore, the required order of given data is 12.807, 12.78, 12.7, 12.087, 12. 08.

PLEASE HELP
12POINTS
Answers
Answer:
C) Number of minutes Lilianna walked
Step-by-step explanation:
Step-by-step explanation:
Lilianna uses \frac{3}{4} calories per minute just by sitting. She uses 1 more calorie per minute by walking.
Liliana uses a total of 12\frac{1}{4} calories walking to the park.
Lilianna uses the equation, d(\frac{3}{4}+1)=12\frac{1}{4} to represent the situation.
Here, variable d represents the time per minute she spends in the park.
and is given as,
d(\frac{3}{4}+1)=12\frac{1}{4}
It can be written as,
d(\frac{3}{4}+1)=\frac{49}{4}
Solving for d,
d(\frac{3}{4}+1)=\frac{49}{4}
\Rightarrow d(\frac{3+4}{4})=\frac{49}{4}
\Rightarrow d(\frac{7}{4})=\frac{49}{4}
\Rightarrow d=\frac{49 \times 4}{4 \times 7}
\Rightarrow d=7
Thus, she spend d= 7 minutes total to the park.

Question 2 options:
8x + 3y = 2
5x + 8y = -11
2x - 4y = -16
y = 5x + 13
-8x - 9y = -17
16x - 4y = 12
12x + 7y = -17
9x + 11y = -7
Answers
Answer:the answer -8x-9y=-17
16x-4y=12
Step-by-step explanation:
divide 16x-4y=12 with 2
8x-2y=12
Then add the equations
-8x-9y=-17
8x-2y=12

Answers
Answer:
x=-10
Step-by-step explanation:
3x-4(2+3x)=82
3x-(4*2)+(4*3x)=82
3x-8-12x=82
-9x-8=82
-9x-8+8=82+8
-9x=90
-9x/-9=x
90/-9=-10
x=-10
Answer:
10 isn't the right answer
Step-by-step explanation:
multiply everything in the parenthesis by -4
you would get 3x-8-12x=82
then combine like terms to get -9x
once your equation is in simplist form it will look like
-9x-8=82
next you add 8 to the 82
-9x=90
then divide 90 by -9 and you would get
x=-10

Answer:
The GCF Of 9 and 12 is 3.
Step-by-step explanation: Okay so first lets multiply! 3x1 Is 3 3x2 is 6 and 3x3 is 9, 3 x 4 equals 12! Since they both can be divided by 3, Example 12 divided by 3= 4 9 divided by 3= 3, therefore they have a GCF of 3. Remember, this is the greatest factor, not Multiple.

Answer:
9) x=3
10)x=8.5
Step-by-step explanation:
Because M is a midpoint, for both questions, the equations on M's either sides are equal.
9) 5x+9=24
Subtract 9 from both sides
5x=15
Divide by 5 on both sides
x=3
10) 3x-7=x+10
Add 7 to both sides and subtract x from both sides
2x=17
Divide by 2
x=8.5

x = 5
The value of x such that f(x) = 7 is 5.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given a graph of a function f(x).
The graph is a straight line where there is a unique value of y for each value of x.
We have to calculate the value of x when y = 7.
Taking the y coordinate to 7, the x coordinate corresponding to the y coordinate is 5.
Hence the value of x is 5.
