You can put this solution on YOUR website! Find an equation of variation where y varies jointly as x and z and
inversely as the square of w and y=20 when x=-0.5, z=4, and w=5.
------------
y = k[(xz)/w^2]
---------
Find "k":
20 = k(-0.5)(4)/5^2
-2k = 20*25
k = -250
---------------
EQUATION:
y = -250xz/w^2
