5-(8v+5) = -4(1+3v)
5-8v-5 = -4 - 12v
-8v = -4 - 12v
4v = -4
v = -1
Answer:
(1,1)
Step-by-step explanation:
Since y=x, we can say x=x^2-x+1. This means x^2-2x+1=0. x=1, y=1, thus your solution is (1,1).
Step 1: Replace f(x) with y: y=-8-5x
Step 2: Switch X and Y: X=-8-5y
Step 3:Solve for y: x+8=-5y ≈ y=(x+8)/-5
Step 4: Replace y with F^-1(x): f^-1(x)=(x+8)/-5 :)
