Select all the correct answers.
select all relations that represent functions.

option A

option C

option D

Step-by-step explanation:

A function is a special relationship where each input has a unique output.

There could not be different y values for same value of x but it may have two x-values assigned to the same y-value.

In option B

for x = 6

have two different outputs y = -6 and y = -1 REJECTED

In option E

for x = 0

have two different outputs y = 0.5 and y = 2 REJECTED

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
