Y varies inversely as x . If x = 4 then y = 9. Find y when x = 3.

Anyone help?

12

Step-by-step explanation:

Given, x and y are inversely proportional.

So, the equation is xy=k, where k is the constant of proportionality

x=4, y=9. plug in the values to find k.

k=4*9 = 36

When x=3, y = k/x =36/3 = 12

y=12, when x=3
