Find the average between the 2

Answer 2

that didnt work!! @FutureMathProfessor

Answer 3

What did you get for an answer?

Answer 4

5 , -5, 0, and not enuf info

Answer 5

So you got 4 answers?

Answer 17

Find the mean then

Answer 18

can you just get me instructions on how to get it @FutureMathProfessor

Answer 19

Do you know how to find the mean?

Answer 20

yes @FutureMathProfessor

Answer 21

Do it then

Answer 22

the axis of symmetry is in between the zeros ....

what value is in the center between -5 and 5 ?

Answer 23

zero

Answer 24

then that is your axis of symmetry: x = 0

Answer 25

why thank you ! ;)

Answer 26

Yup that was it.................

Answer 29

i guess smh

Answer 30

add the values and divide in half
