If y varies inversely with x, and y is 8 when x is 5, find y when x is 2.

y = 20

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = ← k is the constant of variation

To find k use the condition y = 8 when x = 5, then

k = yx = 8 × 5 = 40

y = ← equation of variation

When x = 2, then

y = = 20

15% chance.
