If y varies inversely with x, and y = 8 when x = 3, find y when x = 10.

show all !

y = 2.4

Step-by-step explanation:

Given 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 = 3

k = yx = 8 × 3 = 24

y = ← equation of variation

When x = 10, then

y = = 2.4

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
