Question

Suppose that y varies jointly with w and x and inversely with z and y = 32- when w = 6, x = 20, and z = 3. Write the equation that models the relationship

Answer 1

d

Explanation:

d

Answer 2

Y directly proportional to WX and inversely to Z.

Y=k(WX)/Z
Where k is the constant of proportionality.
So, the first thing is to find the value of this constant.

k = YZ/WX
= (32×3)/(6×20)
= 96/120
= 0.8
The equation that models the relationship will be;
Y = 0.8(WX/Z)
