Yis inversely proportional to x.

when x=3, y=8.

work out the value of y when x=8

y = 3

Step-by-step explanation:

given y is inversely proportional to 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 = 8, then

y = = 3
