Question

Suppose that y is inversely proportional to x.

Find the constant of proportionality k if y = 14 when x = 8.
k =_______

 
Using the k from above write the variation equation in terms of x.
y =_________

Using the k from above find y given that x = 12.
y =

Answer 1

y = k/x for inverse proportions.

 

14 = k/8

 

then k = 14•8 =112

 

y = 112/12 = 28/3 or 9 1/3
