y varies inversely as x and y=4.75 when x=0.52

Question

Find an equation of variation for the given situation

Answer 1

y varies inversely with x:

y = k/x   where k is constant of proportion

 

using given values of x and y find value of k

 

4.75 = k/0.52

k = 4.75(0.52) = 2.47

 

y = 2.47/x

 

If the variance had been direct instead of inverse the problem

would have been set us as y = kx.  Questions?
