Which expression are equivalent to 8-4(-x+5)

4x -12

Step-by-step explanation:

8-4(-x+5)

Distribute

8 -4*-x  -4*5

8 +4x -20

Combine like terms

4x -12

4 (x - 3)

Step-by-step explanation:

Simplify the following:

8 - 4 (5 - x)

-4 (5 - x) = 4 x - 20:

4 x - 20 + 8

Grouping like terms, 4 x - 20 + 8 = 4 x + (8 - 20):

4 x + (8 - 20)

8 - 20 = -12:

4 x + -12

Factor 4 out of 4 x - 12:

4 (x - 3)

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
