Answer:
Yes, 500 texts.
Step-by-step explanation:
If you write out the equations, you can just set them up equal to each other and simplify.
A = .05x + 20
B = .07x + 10
.05x + 20 = .07x + 10 (subtract 10 from both sides)
.05x + 10 = .07x (subtract .05x from both sides)
10 = .02x (multiply both sides by 50
x = 500 texts

Answer:
see explanation
Step-by-step explanation:
note that f ○ g = f(g(x))
To evaluate substitute x = x³ into f(x)
f(g(x)) = f(x³) = 5x³ - 8
In the same way
g ○ f = g(f(x))
To evaluate substitute x = 5x - 8 into g(x)
g(f(x)) = g(5x - 8) = (5x - 8)³
