Since 3/4 of 20 is 15, 15 is 3/4 of tank.

Then since the tanked is being filled at a unit rate of 2 I would do 2 * 7.5 which is 15 :D Yay!

Then I would do 1 * 7.5 which is 7.5

So, the tanked would be filled at 3/4 in 7.5 minutes or 7 1/2 a minute.

Select the correct answer.<br> Which function is the inverse of f(x) = -x^3 - 9?
joja [24]

Answer:

(2)

Step-by-step explanation:

Let f(x) = y → f-¹(x) = f(y) = x, f(y) is the inverse of f(x)

Thus,

=> -x³ - 9 = y

=> - y - 9 = x³

=> (-y - 9)^(1/3) = x

=> f(y) = x

Inverse is (-y-9)^(1/3)

Replacing the variable, inverse is (-x-9)^(1/3)

Option (2)
