Suppose that y varies inversely with x , and y=5 when x=4

Question

write an inverse variation that relates x and y

write an inverse variation equation that relates x and y

Answer 1

y = k/x

where k is the constant of variation.

Using the given information that y = 5 when x = 4, we can substitute these values into the equation to solve for k:

5 = k/4

k = 20

Therefore, the inverse variation equation that relates x and y is y = 20/x.
