Question

. f(x) varies inversely with x and f(x) = –10 when x = 5. What is the inverse variation equation?

f(x) = -2/x
f(x) = -50/x
f(x) = -0.5/x
f(x) = -5/x

Answer 1

@Nnesha could you help me solve this one?

Answer 2

same like last one
f(x) can be written as y
f(x) = y
so use same equation and find k first

Answer 3

nope you don't have to divide ........
first replace f(x) by -10 and x by 5

Answer 4

let me know after that
