Rational Equations:Question 8

If y varies inversely with x and x=2.5 and y=100, what is x when

y=25?

50

Step-by-step explanation:For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5 (2) = 10. Thus, the equation describing this inverse variation is xy = 10 or y =. Example 1 : If y varies inversely as x, and y = 6 w
