Question

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

Answer 1

Answer:
V
=
2

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

Answer:

v = 2

Step-by-step explanation:

If p = $\frac{8}{v}$ is the inverse variation equation then we have to find the value of v if p = 4

p =  $\frac{8}{v}$

We will inverse the equation first.

$\frac{1}{p}$ =  $\frac{v}{8}$

By cross multiplication.

v =  $\frac{8}{p}$

If p = 4 then

v =  $\frac{8}{4}$

v = 2
