If y varies inversely as x and y=2 when x =25 find x when y=40.

Sagot :

Ok, since y varies inversely as x , the equation is y=k/x....... Then you plug in 2 for y and 25 for x to find K....... After that you get K= 50...... Then plug in 50 for K and 40 for y then solve for x....... After that you get X= 1.25!!!!! :)
