Determine the equation of the inverse of y=1/4x^3-2
dedylja [7]

<u>Answer</u>


y⁻¹ = ∛(4x+8)



<u>Explanation</u>

y=(1/4)x³ - 2.

To find the inverse of this equation, you first make x the subject of the formular.

y=(1/4)x³ - 2

Multiply both sides by 4;

4y = x³ - 8

Add 8 on both sides of the equation;

4y + 8 = x³

x³ = 4y + 8

Apply the cube root on both sides to get the value of x;

x = ∛(4y+8)


The inverse of y=(1/4)x³ - 2 is;

y⁻¹ = ∛(4x+8)

Ellie runs 5/6 mile in 10 minutes.what is ellie's speed in miles per minute?
olganol [36]

Answer:

1/12 miles/minute

Step-by-step explanation:

To figure out how fast ellie runs in 1 minute, we can set up this equation:

5/6 = 10x (x being the speed per minute)

We can divide both sides by 10

5/60 = x

Then simplify the fraction to get:

1/12 = x
