Question

do these pairs of values (x and y) represent two quantities that are proportional? x. y3. 125. 206. 249. 36

Answer 1

Info given

We have the following info given

x. y

3. 12

5. 20

6. 24

9. 36​

Solution

In order to see if the two quantites are prportional we can check the following:

k=y/x

If we analyze the first pair of values we have:

k= 12/3=4

And for the next pairs we have:

k= 20/5=4

k= 24/6=4

k=36/9=4

So then as we can see the value of k is the same so then we can say that x and y are proportional since for each unit that x increase y increase 4 units
