I need the solution and the work for it... for each of the multiple choices.

Vlad1618 [11]

For this case we have the following equation:

$x ^ 3 = 375$

We must find the value of "x":

We apply cube root on both sides of the equation to eliminate the exponent:

$x = \sqrt [3] {375}$

We can write 375 as $5 ^ 3 * 3$

So:

$x = \sqrt [3] {5 ^ 3 * 3}\\x = 5 \sqrt [3] {3}$

Then, the correct options are:

$x = \sqrt [3] {375}\\x = 5 \sqrt [3] {3}$

Option A and B

Which equation represents the graph of the linear function?

Flura [38]

Since the line is going from the top left to the bottom right, the slope is negative so A and B are possible answers.

the line crosses the y axis at -1
B is the option that ends with -1

therefore your answer is B. y = -2x - 1
