Suppose that x and y vary inversely and that y=1/6 when x=3. write a function that models the inverse variation and find y when x=10.

y = 1/20 when x = 10

Explanation:

We know that x and y vary inversely and when .

So we can write the function of an inverse variation as:

∝

Finding the constant :

Now finding the missing value :

Therefore, the missing value is .
