Question

When x = 2 and y = 3, z = 42. Write the function that models each of the following relationships.

1. z varies inversely with x and directly with y.

z=y/x
z=28y/x
z=(28y)x
z=3y/2x

Answer 1

formula would be z = ky/x

substitute:

x = 2
y = 3
z = 42

formula becomes:

42 = k*3/2

solve for k to get:

k = 2*42/3 = 28

Answer 2

so it is z=(28y)x?

Answer 3

yes
