Question

Suppose that x and y vary inversely and that x = 2 when y = 8. Write the function that models the inverse variation.

Answer 1

Inverse variation equation is
\[\large y=\frac{k}{x} \implies xy=k\]
so, just plug in x=2, y=8 and find the value of k.

Answer 2

can you find 'k' =.... ?

Answer 3

@yourstruelya ?

Answer 4

you just have to multiply x and y to get k.
k= xy= 8*2 = ... ?

Answer 5

16. lol sorry, I felt it open and walked in the other room.

Answer 6

yes, so your equation is just
xy=16
got it ?

Answer 7

felt it open and walked in the other room again ?

Answer 8

anyways, this is done, the function is xy=16.
hope you got it.
