Answer:500
Step-by-step explanation:
Step by step
If you read the inequality from center to left you get -2x - 8 < -44 then from center to the right it is -2x - 8 >= -8 you get D.
Answer is choice D.
F(x) = 5x + 6
let y = f(x)
y = 5x + 6 solving for x.
y - 6 = 5x
5x = y - 6
x = (y - 6)/5
Recall f(x) = y. Implies x = f⁻¹(y)
<span>x = (y - 6)/5
</span>
f⁻¹(y) <span>= (y - 6)/5
</span>
So as well:
f⁻¹(x) <span>= (x - 6)/5</span>
