Inverse Variation for 100
The variables x and y vary inversely. Use the given
Values to write an equation relating x = 3/4 and y= 3/8.
Then find y when x = 2
y = 9/32x;
9/64
Inverse
Variation for 200
The y varies directly with x. Use the given
Values to write an equation relating x = -2 and y= 5.

Inverse and
Joint
Variation for 400
When you stand on snow, the average pressure P ( psi) that
you exert on the snow varies inversely with the total area of
A (sq in) of the soles of your footwear. Suppose the
pressure is 0.43 psi when you wear snow shoes with total
area of 60 sq inches. Write an equation the given P as a
function of A.
