Does the mapping diagram represent a function? Why or why not? х

O A. No; the output value y=-4 pairs with two different input values.
B. No; each input pairs with only one output.
C. Yes; each input pairs with only one output.
D. No, the input values x = -7 and
x= -1 are paired with the same output value.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
