Only the bottom one of the yes and no I already got the diagram answer.

C. and yes.

Step-by-step explanation:

The diagram answer you chose is incorrect due to the inconsistencies with the x and y coordinates.

All x's should be on one side and the y's should be on the other, hence why C is the correct one instead.

As for if this is a function, yes it is. This is because all inputs (x's) all go to one output (y's).

1 C

Step-by-step explanation:

First set is {1,2,3,4,5} /domain and range is { 13,17,19,23}

answer:   2 multiplied by x =24

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
