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

Question

hartnn · Answer

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.

hartnn · Answer

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

hartnn · Answer

@yourstruelya  ?

hartnn · Answer

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

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

hartnn · Answer

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

hartnn · Answer

felt it open and walked in the other room again ?

hartnn · Answer

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