Which table shows a proportional relationship between x and y?

1# x 3 4.5 8 12
y 2 3 4 8

2# x 1 4 5 10
y 15 60 70 120

3# x 8 12 14 16
y 2 3 4 5

4# x 1 2 5 7
y 5 10 25 35

Table #4

Step-by-step explanation:

We know that if two quantities x and y are proportional it mean their ratio is proportional.

i.e.

For table 1# x 3 4.5 8 12

                    y 2 3 4 8

Here ,

But 1.5 ≠0.67.

⇒ This table does not show a proportional relationship between x and y.

For table 2# x 1   4   5   10

                   y 15 60 70 120

Here ,

But 14 ≠ 15

⇒ This table does not show a proportional relationship between x and y.

For table 3 # x 8  12  14   16

                  y  2  3  4     5

Here ,

But 0.286 ≠ 0.25

⇒ This table does not show a proportional relationship between x and y.

For table 4# x   1  2    5   7

                    y   5 10 25 35

Here ,

⇒ This table shows a proportional relationship between x and y.

Hence, table #4 shows the a proportional relationship between x and y.

answer:   rlly

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
