Represent the following sentence as an algebraic expression, where "a number" is the letter x. You do not need to simplify.

My name is Ann [436]

<h3>Answer: (2x)^3</h3>

Work Shown:

x = some unknown number

2x = twice the number

(2x)^3 = cubing the previous result

If you want to simplify this expression, then you would get 8x^3 since 2^3 = 8.

Which pair of expressions represents inverse functions?

faust18 [17]

In this question , we have to find, which option represents inverse functions.

Let's check out option b

Let it be y

So we have

$y = \frac{x+3}{4x-2}$

Switching x and y and solving for y,

$x = \frac{y+3}{4y-2}$

Performing cross multiplication

$4xy -2x = y+3$

Combining like terms

$y(4x-1) = 3+2x$

$y = \frac{2x+3}{4x-1}
\\
f^{-1} (x) = \frac{2x+3}{4x-1}$

Which is same as of the other function.

So correct option is b .
