10
2
3
15
4
20

25
Does this table of numbers represent a proportional relationship? (1 point)
O
a
No, because the price of 3 boxes should be $11
Ob
No, because the price of 4 boxes should be $40
ос
Yes, because 5 times the price is the number of boxes
Od
Yes, because the price is 5 times the number of boxes

D. Yes, because the price is 5 times the number of boxes

Step-by-step explanation:

To know if they are proportional check to see if there is a number common to the relationship between the y and x to all the numbers:

10/2=5

15/3=5

20/4=5

25/5=5

There is a relationship of 5 and the 5 is multiplied to the x=boxes.

Yes, because the price is 5 times the number of boxes

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

true !
