Answer:

m = 36

n = 3

Explanation:

y varies inversely with x can be written as y ≅ 1/x. As x goes up, y will go down. We need a factor, N, to account for how much change occurs with each step. There needs to be a factor involved, F, to account for how much change occurs with each step.

Calculate the factor by using one of the known points. I'll use (8,9):

y = F/x

9 = F/8

F = 72

The relation becomes y = 72/x. Check this on the other given point, (12,6):

y = 72/x

6 = 72/12 ? YES

Now use y = 72/x to find the two missing points, (m,2) and (24,n):

(m,2) 2 = 72/m, m = 36

(24,n) n = 72/24; n = 3
