There are three answers to the question above, #1. !

((2,-5),(4,-5),(6,2),(8,3))

((-1,5),(3,5),(6,5),(9,5))

((0,3),(4,2),(-1,7),(0,3))

Step-by-step explanation:

For a set of ordered pairs to be a function, no x value can have two different y values.  

In the three functiosn above, every x value has one and only one y value corresponds with it.

((0,3),(4,2),(-1,7),(0,3)) Is still a function because when x is zero, there is only one y value that corresponds with it, which is 3.  

x= 149. 24+7=31. 180-31=149

your welcome

the answer is 0.3175 hope that you ^w^
