Answer: -0.5
Step-by-step explanation:
We can see that at x=0 that Y=2, when x=2, y=1, so we do the x1 - x2 = -2 and y1-y2 = 1
Then we do 1 / -2 = -0.5
The average rate of change is -0.5
To use the elimination method, you have to create variables that have the same coefficient, then you can eliminate them.
Answer:
m + 4
Step-by-step explanation:
I think you mean divide. Is that correct? If it is not leave me a note in your comments.
m^2 + 14m + 40
=============
m + 10
(m + 4)(m + 10)
============
m + 10
Cancel m + 10 on both the top and bottom
m + 4 is your answer.
Answer:
the answer is (0, 4)
Step-by-step explanation:
just count
Answer: 12.5
You start with the equations "2x +2y=38" and "6+x=y". By adding and subtracting in the second equation, you get "2x +2y=38" and "x-y=-6". When you multiply the second equation by 2, you get "2x-2y=-12."
subtracting the equations "2x +2y=38" and "2x-2y=-12" gets you to "4y=50", where you have to divide two sides by 4 and get "y=12.5"
