Question

Given that y varies inversely as x, and y = 8 when x = 3, what is the value of y when x = 12?

Answer 1

Answer:

"y=32"

is the answer

Step-by-step explanation:

x=3 > y=8

x=3+3+3+3=12 then y=8+8+8+8=32

Answer 2

Answer:

y = 2 when x =12

Step-by-step explanation:

y = k/x ..............as y varies inversely as x

8 = k/3

k = 8 * 3

k = 24

So,

y = k/x

y = 24/12

y = 2
