Question

I AM GIVING AWAY ALL OF MY 30 POINT AWAY IF SOMEONE ANSWERS THIS QUESTION

Answer 1

8.7

9.3

Explanation:

Answer 2

a) x and y are not inversely proportional because for each value of x and y we don't get k=yx

b) x and y are inversely proportional because for each value of x and y we get k=yx

If x and y are inversely proportional enter the constant of proportion: 30

Explanation:

a) To check if x and y are proportional or not, we would find
`k=yx`

For each value of x and y, their product should be equal to k a constant.

So,

x y k=yx

3 8 24

4 6 24

5 4.8 24

5.5 4 22

So, x and y are not inversely proportional because for each value of x and y we don't get k=yx

b) To check if x and y are proportional or not, we would find
`k=yx`

For each value of x and y, their product should be equal to k a constant.

So,

x y k=yx

0.1 300 30

0.5 60 30

75 0.4 30

100 0.3 30

x and y are inversely proportional because for each value of x and y we get k=yx

If x and y are inversely proportional enter the constant of proportion: From above table we get k = 30 so, Constant of proportion is: 30
