Question 40627: please help
if y varies inversely as x, and y=12 when x=6, what is k, the variation constant?

You can put this solution on YOUR website!
Start with:
y+=+k%2Fx and substitute: y = 12 and x = 6, then solve for k.
12+=+k%2F6 Multiply both sides by 6.
72+=+k
The constant of variation, k, is 72
