The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.
You would use the distance formula
d = rt
Scine you need to find the rate you will use r = d/t
r = 220/5
r = 44
Answer:
-2x^2-5x+16
Step-by-step explanation:
Remove parenthesis:
-10x^2+9+8x^2-5x+7

= -2x^2-5x+9+7
=-2x^2-5x+16
