In two or more complete sentences, explain how to solve the cube root equation, <img src="https://tex.z-dn.net/?f=%20%5Csqrt%5B3
nordsb [41]
Isolate the root expression:

\sqrt[3]{x+1}+2=0\implies\sqrt[3]{x+1}=-2

Take the third power of both sides:

\sqrt[3]{x+1}=-2\implies(\sqrt[3]{x+1})^3=(-2)^3

Simplify:

(\sqrt[3]{x+1})^3=(-2)^3\implies x+1=-8

Isolate and solve for x:

x=-9

Since the cube root function is bijective, we know this won't be an extraneous solution, but it doesn't hurt to verify that this is correct. When x=-9, we have

\sqrt[3]{-9+1}=\sqrt[3]{-8}=\sqrt[3]{(-2)^3}=-2

as required.

After driving for 20 minutes, Juan was 62 miles away from his apartment.

After driving for 32 minutes Juan was only 38 miles away.

The time driving and the distance away from his apartment form a linear relationship.

To find:

The independent and dependent variables.

Solution:

If the value of a variable depends on the another, then it is called dependent variables.

If the value of a variable does not depend on the another, then it is called independent variables.

In the given problem, the distance of Juan from his apartment depends on the time he drove. So,

Dependent variable = Distance of Juan from his apartment in miles.

Independent variable = Time he drove
