Question

Suppose y varies inversely with x, and y=3 when x=8

write an equation that models the variation
find y when x=72
PLEASE SHOW YOUR WORK

Answer 1

y=1/3

Explanation:

y is inversely proportional to x

y=k/x. where" k" is the constant

substitute in the values of y and x

3=k/8

Cross multiply

k=24

To find y,input the correct values

y=k/x

y=24/72

y=1/3
