# Pls answer now which table shows a proportional relationship between x and y? x 1 3 4 7 y 2 5 8 14 x 2.5 3 5 6 y 5 6 10 15 x 1 2 3 4 y 4 10 12 16 x 7 14 28 35 y 1 2 4 5

The fourth one

Step-by-step explanation:

y=x/2

x 1 2 5 7

y 5 10 25 35

Step-by-step explanation:

The y values are all just the x values times 5

I don't exactly know the answer to 1. and 2, but I do to 3. because I took a test with the same question.

The answer for Number 3. is 'Not Proportional'

Sorry that I couldn't be of help for the other questions.

Second table

Step-by-step explanation:

Proportional relationships between x and y satisfied the following equation y = k*x, where k is some constant. Rearranging we get: k = y/x. So, if we take every pair y-x and divided them, we have to find the same k.

- Division y/x for the first table:

2/1 = 2

5/3

8/4 = 2

14/7 = 2       It is not a proportional relationship

- Division y/x for the second table:

1/7

2/14 = 1/7

4/28 = 1/7

5/35 = 1/7       It is a proportional relationship

- Division y/x for the third table:

4/1 = 4

10/2 = 5

12/3 = 4

16/4 = 4        It is not a proportional relationship

- Division y/x for the fourth table:

5/2.5 = 2

6/3 = 2

10/5 = 2

15/6 = 5/2        It is not a proportional relationship

x 1 2 5 7

y 5 10 25 35

Step-by-step explanation:

The y values are the x values times 5

Second table

The reason why this table doesn’t look proportional is due to the fact that it has a missing part. There should be an extra box of x:21 and y:3, making this graph proportional throughout.

Hope this helps comment below for more questions :)
The answer is d i think so pretty sure it is

x 7 14 28 35
y 1 2 4 5

ratio x : y is 7 : 1

Do u just plot the numbers on the graph like (1,
In factoring by grouping, what would you have for step 3 for the following? step 1: x^3 +5x^2 +4x+20 step 2: x^2 (x+5)+4(x+5) step 3: ?
