Question

Assume that y varies inversely as x. If y = -6 when x = -2, find y when x = 5.

Answer 1

Express this variation as a formula: y=k/x Where k is the constant of proportionality.

Answer 2

Next find the value of k using the known situation -6=k/-2
We can see that k=12.

Answer 3

We now solve the new condition:

y=12/5=2.40

Answer 4

Were you following the progression with understanding?

Answer 5

Ahh I see now :) thank you.
