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
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.
