Hmmm. Still having trouble with direct/inverse proportionality?
z = ky/x
-10 = k(5)(50)
k = -1/25
Can someone please help me with this question:
Write an equation that describes the following variation statement, and then find the constant of proportionality k . z is inversely proportional to x and directly proportional to y ; z = -10 when x = 5 and y = 50.

oops -10 = k(50)/5
k = -1
k = -1
