Answer:
.
Step-by-step explanation:
I'm pretty sure it would be y=2x+9
Answer:
-1
Step-by-step explanation:
The mean is the sum of all values divided by the amount of values.
We take the sum of all the numbers:
-3 + -8 + 12 + -15 + 9
-11 + 12 + -15 + 9
1 + -15 + 9
10 + -15
-5
We then divide the sum by how many number we have (we are given 5 numbers):
-5/5 = -1
Therefore, our mean is equal to -1.


multiply both sides by .4 to isolate the x variable.

x = 1.6

Hi there!
If you are 15 right now, you would use the expression: 15+12=y
