Step-by-step explanation:
Add all of the numbers together
7 + 9 + 0 + (-9) + (-7)
simplify it down to:
(7+9+0)= 16
-9 + (-7)= - 16
So, -16 + 16 = 0
then divide 0 by 5 to get the answer of 0
To find the mean you have to add all of the numbers together and then divide by the amount of numbers that you have.
Answer:
y = 2x + 2
Step-by-step explanation:
just trust me i took test and it had this question on it lol
Answer:
Step-by-step explanation:
4y = 2(y - 5) - 2
4y = 2y - 10 - 2
4y - 2y = -12
2y = -12
y = -12/2
y = -6 <===
(-2) + 6 + 1 = 1 + 6 + (-2)
-2 + 7 = 7 - 2
5 = 5
