Question

y varies inversely with x and y = 5 when x = 2.

Which is the inverse variation equation for the relationship?

y=2x

y= x + 2

y = 1/2x

y = 10/x

Answer 1

are the coords (2,5) a points on the inverse equation

Answer 2

actually that doesn't even matter... the inverse is equal to the original in this special case

Answer 3

Plug in x and y... there's only one equation that satisfies the values

Answer 4

yes, the inverse variation equation witch is f(x) = k/x

Answer 5

so if i put in what they gave me i would get

Answer 6

y= 10/x, since when x=2, y=5...

Answer 7

@Nnesha is y = 10/x right?

Answer 8

because then i would mutiply 2 times 10 and that would = k

Answer 9

yes right
good job :)

Answer 10

sorry 2 times 5

Answer 11

yes :)

Answer 12

thanks

Answer 13

np :)
