Which set of ordered pairs represents a function? {(-4,9),(-5,4), (-5, -2), (1, -6)}

{(2,6), (5,1), (9,4),(2,-6)}

{(-7,-8), (0,1),(-3,9), (-4, -8)}

{(-6, -5),(-3,-4), (6,6), (-3,8)}

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less

step-by-step explanation:

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
