The value of x when y is 8 is 9.75.

It is given that

y ∝ 1/x

y = k/x......(1)

Where k is a constant of proportionality

What is the constant of proportionality?

The constant of proportionality is the ratio that relates two given values.

When y =13, x=6

Means, 13 = k/6

k = 78

Putting the value of k in equation (1)

y = 78/ x

8 = 78/ x

x =9.75

Therefore, The value of x when y is 8 is 9.75.
