I think it proved by the arc intercepting kl making it an interior alternate angle which means it equal to each other
The solution to this is 3(8)-3(9).
F* you B*!!!!!! Your so S*! That's the easiest thing in the world!!
Answer:
if 8 people take 10 hours then
1 people 10 / 8 = 1.25 hours
then 14 people =
14 * 1.25 = 17.5 hours

![\large\boxed{Q2.\qquad C.\ -2x+y=-2}\\\boxed{Q4.\qquad C.\ y=3x+12}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7BQ2.%5Cqquad%20C.%5C%20-2x%2By%3D-2%7D%5C%5C%5Cboxed%7BQ4.%5Cqquad%20C.%5C%20y%3D3x%2B12%7D)
Step-by-step explanation:
Q2:
The point-slope form of an equation of a line:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
m - slope
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have the points (4, 6) and (6, 10). Substitute:
![m=\dfrac{10-6}{6-4}=\dfrac{4}{2}=2](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B10-6%7D%7B6-4%7D%3D%5Cdfrac%7B4%7D%7B2%7D%3D2)
<em>use distributive property</em>
<em>add 6 to both sides</em>
<em>subteact 2 from both sides</em>
![-2x+y=-2](https://tex.z-dn.net/?f=-2x%2By%3D-2)
Q4:
The slope-intercept form of an equation of a line:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
m - slope
b - y-intercept
Put the slope m = 3 and the coordinateso f the point (-2, 6) to the point-slope form of an equation of a line:
![y-6=3(x-(-2))](https://tex.z-dn.net/?f=y-6%3D3%28x-%28-2%29%29)
<em>use distributive property</em>
<em>add 6 to both sides</em>
![y=3x+12](https://tex.z-dn.net/?f=y%3D3x%2B12)
