Question

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

Answer 1

Answer:
V
=
2

Step-by-step explanation:
we can rearrange the equation

p
1
=
8
V
←
cross-multiplying gives

p
V
=
8
←
divide both sides by p

⇒
V
=
8
p
=
8
4
=
2

Answer 2

v = 2

Step-by-step explanation:

If p =
`(8)/(v)` is the inverse variation equation then we have to find the value of v if p = 4

p =
`(8)/(v)`

We will inverse the equation first.

`(1)/(p)` =
`(v)/(8)`

By cross multiplication.

v =
`(8)/(p)`

If p = 4 then

v =
`(8)/(4)`

v = 2
