1. The variable y varies inversely with x and y = 6 when x = 3.

Y_Kistochka [10]

Inverse variation means y=k/x, we are given (3,6) so

6=k/3

k=18 so

y=18/x

y=18/27

y=2/3

x = –6

Solution:

Given expression is $\sqrt[3]{x-2}+5=3$ .

Step 1: Isolate the radical by subtracting 5 from both sides of the equation.

$\Rightarrow\sqrt[3]{x-2}+5-5=3-5$

$\Rightarrow\sqrt[3]{x-2}=-2$

Step 2: Cube both sides of the equation to remove the cube root.

$\Rightarrow(\sqrt[3]{x-2})^3=(-2)^3$

Cube and cube root get canceled in left side of the equation.

$\Rightarrow\ x-2=-8$

Step 3: To solve for x.

Add 2 on both sides of the equation.

$\Rightarrow\ x-2+2=-8+2$

$\Rightarrow\ x=-6$

Hence the solution is x = –6.
