Classify the relations according to whether or not they are functions.
x = -3
y = 10
3x + 2x = 3

x = -3: is not a function

y = 10: is a function

3x + 2x = 3: is not a function

Step-by-step explanation:

A function is a set of ordered pairs in which no first coordinate, or x-values, repeat. We can use this to determine the following:

x = -3 is not a function as the x will be repeating for each ordered pair.

y = 10 is a function because though the y is repeating, the x is not.

3x + 2x = 3 is not a function because you can solve it to get x = 0.6 (add 3x to 2x, you get 5x = 3, divide by 5 on both sides and x = 3/5 = 0.6).

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 .
