Is the relations a function? {(2, –4), (–2, 4), (2, 5), (5, –1), (–1, 5)} Select the best answer. a
Yes, the relation is a function
b
No, the relation is not a function. The domain values of –1 and 2 are both assigned to 5.
c
No, the relation is not a function. The domain value of 2 is assigned to both –4 and 5.

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 .

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
