Question

y varies inversely with x, and k (the constant of variation) = 23. What is the value of y when x = 7? Round to the nearest tenth, if necessary.

Answer 1

Hello!

The constant of variation is xy. XY=23. If X=7 then Y=23/7.

So as we can see, the stated inverse variation can be represented as the equation y = k/x. ===> k = 23 & x = 7 ⇒ y = 23/7. <====
