Question

For the inverse variation equation p=8/v, what is the value of V when p = 4?

a.1/8
b.1/2
c.2
d.32

Answer 1

it is 2

Explanation:

4=8/v

4v=8

v=2

Answer 2

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form

`y*x=k \ or\ y=k/x`

in this problem we have that

the value of the constant K is equal to
`8`

so

`PV=8`

Solve for V

`V=8/P`

Find the value of V for
`P=4`

substitute the value of P in the formula

`V=8/4=2`

therefore

the answer is

the value of V is equal to
`2`
