Find f(x-7) if f(x)=-3x+2

f(x-7)=-3x+23

Step-by-step explanation:

f(x-7)= -3(x-7)+2

= -3x+21+2

f(x-7)=-3x+23

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.
