Which table of ordered pairs represents a proportional relationship?

The last one y = -4 x

Last choice

The first one is y=x^2

The second one almost is y=2x but the last entry doesn't work.

The third one doesn't have any apparent proportionality

The way to find out is, for each table, divide each y-coordinate by its corresponding x-coordinate. If all the divisions give you the same answer, that relationship is proportional.

A. 4/-2 = -2

16/-4 = -4

Two divisions are already different. A. is not the answer.

B. -8/-4 = 2

-12/-6 = 2

-18/-8 = 2.25

Not all quotients are equal. B. is not the answer.

C. 5/-3 = -5/3

3/-5 = -3/5

Quotients are not equal. C. is not the answer.

D. 12/-3 = -4

24/-6 = -4

36/-9 = -4

All quotients are equal.

D.

what does muffins have to do with anything?

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
