Answer:
x+4y=-35
-8x-4y=28
Step-by-step explanation:
The answer to the original equations is (1, -9). You can solve that by using substitution by moving the 4y over and substituting that equation for x on the second part of the top equation. Using elimination, the second set of answers will give you the same, (1, -9)!
-14, -2 and 0 opposite intergers
In interval <a, b> the average rate of change the function you count from this formula:

Here you've got a=-1 and b=1:
Answer:
because your just adding a zero at the end.
Step-by-step explanation:
Answer:
y=2x+6
Step-by-step explanation:
to write the equation you just need to plug in numbers
y=mx+b
the m is the slope and the b is the y intercept
