Do the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the table. direct variation; y = 40 pi direct variation; y = 1/40 x inverse variation; xy = 40 inverse variation xy = 1/40

Solution

Solution:
(c)Given data represents inverse variation as x increases (1,2,5,10) y decreases (40,20,8,4)and also xy = 40 for every value of x and y.

For x = 1
y = 40
xy = 40

For x = 2
y = 20
xy = 40
