Consider the line y = 7x-5.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Answer:
[tex]\boxed {\sf Parallel: 7 }[/tex]
[tex]\boxed {\sf Perpendicular: -\frac{1}{7}}}[/tex]
Step-by-step explanation:
First, identify the slope.
We are given the line y=7x-5.
This is in slope intercept form or y=mx+b where m is the slope and b is the y-intercept. So, the coefficient to x, or 7 in this case, is the slope.
m=5Now, find the parallel and perpendicular slopes.
1. Parallel Slope
Parallel lines never intersect, so they have the same slope. A parallel line has a slope of 7.
2. Perpendicular Slope
Perpendicular slopes intersect to form right angles. They have negative reciprocal slopes.
Negate the slope: 7⇒ -7 Find the Reciprocal (flip the numerator and denominator: -7/1 ⇒ -1/7A parallel line has a slope of 7 and a perpendicular line has a slope of -1/7.
Answer:
I'll help
Step-by-step explanation:
Parallel lines have the same slope so it will be 7.
And perpendicular lines if you multiply them together they have to add up to -1,
So 7 you change it to its opposite which is 1 over 7 and yeah just
Find the intersection points of the parabola y=−3x2−2x+2 and the line 10x−y=−11. Give your answer as two ordered pairs separated by a comma. For example, if you found that the solutions were (1,2) and (3,4) you would enter (1,2),(3,4).
Answer:
(-1,1),(-3,-19)
Step-by-step explanation:
y=−3x²−2x+2 (1)
10x−y=−11
y=10x+11 (2)
−3x²−2x+2 = 10x+11
3x² + 12x + 9 = 0
x² + 4x + 3 = 0
(x + 1)(x+3) = 0
x= -1 or x = -3
y = 1 or y = -19
The solutions of the equations y = −3x² − 2x + 2 and 10x − y = −11 will be (-1, 1) and (-3, -19).
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equations are given below.
y = −3x² − 2x + 2 ...1
10x − y = −11 ...2
From equations 1 and 2, then we have
10x + 11 = −3x² − 2x + 2
3x² + 12x + 9 = 0
x² + 4x + 3 = 0
x² + 3x + x + 3 = 0
x(x + 3) + 1(x + 3) = 0
(x + 3)(x + 1) = 0
x = -1, -3
The value of y at x = - 1 is given as,
y = 10(-1) + 11
y = 1
The value of y at x = -3 is given as,
y = 10(-3) + 11
y = - 19
The solutions of the equations y = −3x² − 2x + 2 and 10x − y = −11 will be (-1, 1) and (-3, -19).

Actually Welcome to the Concept of the Parallel lines.
To make them parallel ,just equate them.
5x = 3x + 60
===> 5x - 3x = 60
===> 2x = 60
.hence, x = 30
====> x = 30
The value of x for which A || B is 15° as they are pair of alternate angles.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
Given, are two alternate angles 5x and 3x + 60, the lines A and B will be parallel if the sum of these two angles is 180°.
∴ 5x + 3x + 60 = 180°.
8x = 120°.
x = 120/8.
x = 15.

The ratio of the number of boys to the number of girls in a certain class is 8:5. if the number of boys in that class is 52 students . find the number of girls?
Answer:
34.5
Approximately= 35
Step-by-step explanation:
The ratio of the number of boys= 8
Ratio of number of girls= 5
Total ratio= 8+5=13
number of boys in that class =52
Let total number of students= X
Ratio of number of boys= 8/13 × X=52
= 8X/13 = 52
8X=13 × 52
8X= 676
X= 84.5
Then, the number of girls= (84.5-50)
34.5
Answer:
the answer is 84.5-50 is the answer

Henry worked for 8 days, Jack worked for 9.5 days while Steffi worked for 6.5 days to complete a project. If the amount earned for the project completion was shared among them in the ratio of the number of days each one had worked, find the ratio in which the amount was shared.
Answer:
The ratio in which the amount is shared is 16:19:13
Step-by-step explanation:
The given parameters are;
The number of days Henry worked = 8 days
The number of days Jack worked = 9.5 days
The number of days Steffi worked = 6.5 days
The sharing formula for the amount earned for the project = The ratio of the number of days worked by each one
The total number of days worked by all three = 8 days + 9.5 days + 6.5 days = 24 days
The fraction of the total number of days Henry worked = (8 days)/(24 days) = 1/3 = 16/48
The fraction of the total number of days Jack worked = (9.5 days)/(24 days) = 19/48
The fraction of the total number of days Steffi worked = (6.5 days)/(24 days) = 13/48
Therefore. the ratio in which the amount is shared = 16:19:13 (which is the same as the ratio of the number of days worked)
Thirty adults were asked how many pets they have had over their lifetime. The results are shown in the histogram below.
A bar graph entitled Lifetime Pets has number of pets on the x-axis and number of adults on the y-axis. 14 adults had 1-5 pets; 9 had 6 to 10; 5 had 11 to 15; 2 had 16 to 20.
Which of the following is most likely true?
The true statement about the number of pets owned by the thirty adults is (b) The mean and median are both in the interval 6-10
What is an histogram?Histograms are graphs that are used to represent data, where the length of the bars represent the frequency
The data on the histogram are:
14 adults = 1-5 pets;
9 adults = 6 to 10 pets;
5 adults = 11 to 15 pets
2 adults = 16 to 20 pets
The mean is calculated as:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
So, we have:
[tex]\bar x = \frac{14 * 3 + 9 * 8 + 5 * 13 + 2 * 18}{30}[/tex]
This gives
[tex]\bar x = 7.2[/tex]
7.2 is in interval 6 to 10
The median is:
[tex]Median = \frac n2[/tex]
[tex]Median = \frac {30}2[/tex]
[tex]Median = 15th[/tex]
The 15th element is also interval 6 to 10
Hence, the true statement is (b) The mean and median are both in the interval 6-10

Step-by-step explanation:
151 is the outside of the angle so you do 180-151 which is 29 and that plus 32 which is 61 and then 180-61 which is 119
Answer:
x = 119°
Step-by-step explanation:
180° - 151° = 29°
so now we have two angles: 29° and 32°.
32° + 29° + x = 180°
61° + x = 180°
x = 119°

what formula would you use to find the area of this figure?
Step-by-step explanation:
Find the area of a square or rectangle by multiplying the length times the width. This formula looks like l*w. If the length is 5 and the width is 2, the area is 10 square units. Calculate the area of a four-sided shape that is not a rectangle by multiplying the base (one of the sides) by the height.

Answer:
-12 > -24
Step-by-step explanation:
When the numbers are negative the number that is closer to zero is the greatest
Answer:
-12 is greater than -24 or -12 > -24Step-by-step explanation:
Think of a number line, 0 being the middle point separating positive numbers on the right, and negative numbers on the left. The farther left you go down the number line, the smaller the numbers get in value.
With -12 being closer to 0, and -24 being farther down, which makes -24's value decrease. Which therefore makes it smaller.

ratio of leg to hypotenuse in a 45-45-90° triangle is 1 : [tex]\sqrt{2}[/tex]
we can use this proportion to solve the problem:
let 'x' = leg
x/8 = 1/[tex]\sqrt{2}[/tex]
cross-multiply:
