If y varies inversely as x, and y = 3 when x = 6, find the value of x when y = 18.
y = k/x
k = 3 x 6 = 18
18 = 18/x
x = 1
Assume that y varies inversely with x and that y is 2 when x is 4. Which of the following is the equation of inverse variation?
y = k/x
k = 2 x 4 = 8
y = 8/x
xy = 8
Hope this answers the question. Have a nice day.
