Which equation represents a proportional relationship? a) y = 9x b) y = 9x + 1 c) y = 9x + 9 d) y = 9 x

A) y = 9x

Step-by-step explanation:

Proportional relationships shows the relationship between two or more variables where their ratios are equivalent in a given expression. It is majorly a direct relation, which implies that as the value of on variable increases, the value of the other variable also increase.

From the expressions given, the first shows a good proportion between the variables given.

So, y = 9x is the answer.

answer: -8.2562234e+13

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
