Question

help? suppose that y varies inversely with x. write a function that models the inverse function.
x=15 when y = 2
answer choices
a. y= 15/2x
b.y=30x
c.y = 7.5x
d. y=30/x

Answer 1

do you know the equation for inverse variation ??

Answer 2

no

Answer 3

\[y = \frac{ k }{ x }\] equation for inverse variation
where k is constant of variation
so replace x and y by their values and solve for k
