Question

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

Answer 1

We are given:

$p= \frac{8}{v}$

and we are to find the value of v when p = 4. Using this value in above equation, we can write:

$4= \frac{8}{v} \\ \\ 4v=8 \\ \\ v= \frac{8}{4} \\ \\ v=2$

So, for p=4 the value of v will be 2. 
Thus option C is the correct answer

Answer 2

For this case we have the following equation:
 p = 8 / v
 Clearing v we have:
 v = 8 / p
 Substituting the value of p = 4 we have:
 v = 8/4
 Rewriting we have:
 v = 2
