Question

y varies inversely with x. Find the inverse variation equation if x = -2.5 when y = 50.
y/x = -125
xy = -125
y/x = -20
xy = -20

Answer 1

for inverse variation, use this formula

y=k/x meaning that u solve for k to get ur answer

like this u plug in y= 50 and x= -2.5

and solve for k to get ur answer in the above form
