What value of x is line a parallel to line b?

x=20

Step-by-step explanation:

if you need this lol,

6x+60=180

6x=120         6 goes into 12 twice, then add the zero to the end because math

x=20

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
