: Suppose z varies directly as x and inversely as the square of y.
z =
:
When x = 35 and y = 7, the value of z is 50.
Find k using the above values
= z
= 50
=
=
k = * 49
k = 10 * 7
k = 70
Choose the function that models the relationship and z when x = 5 and y = 10
:
z = is the function
z =
z =
z = 3.5
