Answer:
=5x
Step-by-step explanation:
5x(4−2)(2)
−4−(−8)
=5x :)
F(g(x)) = [(-7x-8)/(x-1) - 8} / [(-7x - 8)/(x-1) + 7] =
[(-7x - 8 - 8(x-1)) / (x-1)] / [(-7x - 8 + 7(x-1)) / (x-1)] = (-15x) / (-15) = x.
g(f(x)) = [-7*(x-8)/(x+7) - 8] / [(x-8)/(x+7) - 1] =
[(-7x + 56 -8*(x+7)) / (x+7)] / [(x - 8 - (x + 7)) / (x+7)] = (-15x) / (-15) = x.
So since f(g(x)) = g(f(x)) = x we can conclude that f and g are inverses.
Divide both by 18.

Answer:
y = -2/3x - 2
Step-by-step explanation:
Step 1: Find slope <em>m</em> of perpendicular line
<em>Simply take the negative reciprocal of the given line</em>
m = -2/3
y = -2/3x + b
Step 2: Find <em>b</em>
6 = -2/3(-12) + b
6 = 8 + b
b = -2
Step 3: Rewrite perpendicular equation
y = -2/3x - 2
