Answer 4

suppose that y varies directly with x and at the same time varies inversely with Z, and y=12 when x=6 and z=-2. write an equation that models this relationship.

So the general equation we use to model this is
y = k*x / z

Your task is to find k , by plugging in values.

Answer 5

so y=k * 6/-2?

Answer 6

you are also given y

Answer 7

sorry! 12=k*6/-2?
12=k*-3?

Answer 8

that looks correct

Answer 9

well, the 4 answers I am given are y=-4x/z
y=4x/z, y=-4z/x and y=4z/x
