A. -∞<x<∞ B. -∞<x<∞
Step-by-step explanation:
f(x) = 8x - 5
g(x) = (x+5)/8
(f·g)(x) = f(g(x)) = 8 ((x+5)/8) - 5 = x+5-5 = x
(g·f)(x) = g(f(x)) = ((8x-5)+5) / 8 = 8x/8 = x

Perimeter of a triangle = all 3 sides added together
x + (x - 4) + (x - 4) = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 27/3
x = 9 <==
16 - 2t = t + 9 + 4t
16 - 2t = 5t + 9
-7t = -7
t = 1

Money spent at grocery store = x, money spent at game store = y
x = 24
x = 2y - 6
