Pls help due in an hour
BlackZzzverrR [31]

Answer:

4) Yes

5) Yes

6) Yes

7) No

Step-by-step explanation:

4) When we look at the table in the question, we can see the pattern is comics x 3 = price.

We know the definition of a proportional relationship is when one number is increased, the other is as well. So, it is in a proportional relationship.

5) We do the same thing here, we notice that we can divide the number of bikes by 5 to get the number of trips.

So, this is a proportional relationship.

6) The same reasoning applies to 6, we can see they follow a pattern.

7) All of them can be multiplied by 2, except the last one can't, so this is NOT a proportional relationship.
