1st one is -9x+6, -16x-14, 7x+3,4x-14, 3x+11,-9x-2,24x-40
-1 you change all the x values to -1 and then solve
-14>2x>18
Hope this helps!

Answer:
$2500 - 2%
$1500 - 4%
Step-by-step explanation:
Say the interest for the $2500 is x, so the interest for the $1500 is x+0.02.
As an equation, they would look like this:
2500x+1500(x+0.02)=110
Now solve
2500+1500x+30=110
4000x=80
x=0.02
That means the interest for the $2500 is 0.02, or 2%, and the interest for the $1500 is 0.04, or 4%.
