Answer: First option.

Step-by-step explanation:

Given the following equation provided in the exercise:

$\sqrt[3]{x+8}=-4$

You can follow the steps indicated below in order to find the solution of this equation:

1. Cubing both sides of the equation, you get:

$(\sqrt[3]{x+8})^3=(-4)^3\\\\x+8=-64$

2. Finally you must subtract 8 from both sides of the equation:

$x+8-8=-64-8\\\\x=-72$

You can notice that this solution matches with the first option.

Since there are 6.6 laps in a mile, how many laps will you have to make to run 5 miles?

mezya [45]

Answer:

33 laps

Step-by-step explanation:

we know that

There are 6.6 laps in a mile

using proportion

Find how many laps will you have to make to run 5 miles

Let

x ----> the number of laps

$\frac{6.6}{1}\frac{laps}{mile}=\frac{x}{5}\frac{laps}{mile} \\ \\x=6.6*5\\ \\ x=33\ laps$

PLEASE HELP MEEE ASAP

lys-0071 [83]

Step-by-step explanation:

first of all, g(x) has only negative functional result values (y) except for 0.

and a square is always positive.

so, the only possible right answers are the ones that include a minus ("-") sign.

the graph shows us that g(x) goes through the points (1, -3) and (-1, -3).

so, which equation turns an x = 1 into an y = -3 ?

therefore, the right answer must be D.

g(x) = -3x²

it works for both points :

-3 = -3×1² = -3 correct

-3 = -3×(-1)² = -3×1 = -3 correct
