Fill in the blank. If xy = 20, then y decreases as x _________.
A) decreases
B) increases
C) stays constant
Which equation is the inverse variation relationship for the following quantities? y =12 when x = 5
A) y/x = 2.4
B) y = 2.4x
C) xy = 60
Assume that y varies inversely with x. If y = 3 when x = 2.4, what is y when x = 2?
A) 3.6
B) 0.8
C) 7.2
D) 4.8
These are the questions i dont get on my practice exam....anyone help???
