Answer:

7. x = 4

8. x = 10

Step-by-step explanation:

7. The angles are equal to each other so you can do

40 = 12x - 8

48 = 12x

4 = x

8. The angles add up to be 180 degrees so you can combine them and set them equal to 180

6x + 12x = 180

18x = 180

x = 10

Find the slope and te y intercept y=-5x
babunello [35]
This equation is written in slope intercept form (y=mx+b where m is slope and b in the y intercept).

The m value here is -5 so that is the slope.
The b value here is 0 so the y intercept is at 0.

You can also find this by plugging 0 for the value of x.
y= -5(0)
y= 0
