PLEASE SOMEONE HELP I TRULY DO NOT UNDERSTAND

Hi there!

$\large\boxed{f^{-1}(x) = \sqrt[3]{\frac{x+4}{9} } }$

$f(x) = 9x^{3} - 4$

Find the inverse by replacing f(x) with y and swapping the x and y variables:

$x = 9y^{3} - 4$

Isolate y by adding 4 to both sides:

$x + 4 = 9y^{3}$

Divide both sides by 9:

$\frac{x+4}{9}= y^{3}$

Take the cube root of both sides:

$y = \sqrt[3]{\frac{x+4}{9} }\\\\f^{-1}(x) = \sqrt[3]{\frac{x+4}{9} }$

Solve the rational equation: x/x+1 = 2/x+1

Tju [1.3M]

Answer:

x = 2

Step-by-step explanation:

$\frac{x}{x+1} =\frac{2}{x+1}$

x ≠ 0

x ≠ - 2

x ≠ - 1

$\frac{x}{x+1}(x+1) =\frac{2}{x+1}(x+1)$

x = 2

First, rewrite 14/25 and 11/20 so that they have a common denominator. Then, use <, =, >

muminat

Answer: 14/25 = 56/100

11/20 = 55/100

14/25 > 11/20

Step-by-step explanation:

The least common multiple of 20 and 25 is 100.

(100 = 20*5, 25*4)

So we can take the common denominator 100.

14*4/25*4 =56/100. ∴14/25 = 56/100

11*5/20*5 =55/100. ∴11/20 = 55/100

56>55

∴56/100 > 55/100

∴14/25 > 11/20

Hope it's good;)
