Question

Write the inverse variation equation of the following. Y varies inversely with x and y = -12 when x = 6.
A. xy = -2
B. xy = -72
C. xy = -0.5

Answer 1

is Y different from y?

Answer 2

umm...it's possible

Answer 3

y=k/x

yx=k

Answer 4

ill just assume they're equal so the first equation is

y = k/x

-12 = k/6
k = -72

so y = k/x
y = -72/x
xy = -72

Answer 5

oh okay i think i get how to do it now...thnk u igba and shadowone.
