Question

The variables x and y vary inversely. Use x = 4 and y = 8 to write an equation relating x and y. Then find y when x
= 2.

Answer 1

Answer:

1. y=
2. $\frac{32}{x}$
3. 16

Step-by-step explanation:

y=

$\frac{k}{x}$

when x=4 and y = 8

k =xy

k=4×8=32

:- y=

$\frac{32}{x}$

when x = 2

y=

$\frac{32}{2}$

:- y = 16
