Answer:

x = 20

Step-by-step explanation:

since the triangle is a right angle, that means the angle is 90 degrees

equation:

30 + 3x = 90

subtract 30 on both sides

30 - 30 + 3x = 90 - 30

3x = 60

then divide each side by 3

\frac{3x}{3} = \frac{60}{3}

x = 20

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)
