Answer:$1
Step-by-step explanation:
15-10=5 +4=9 -8= $1
Set the equations to equal each other:
-2x²+1=-2x+1
Solve for x:
-2x²+1=-2x+1
-2x²+2x+1=-2x+2x+1
-2x+2x+1-1=1-1
-2x²+2x=0
2x (-x+1)=0
2x=0 and -x+1=0
2/2x=0/2 -x+x+1=0+x
x=0 1=x
There are two solutions, x=0,1
1) Associative
2) Reversal
3) Addition
4) Commutative
5) Multiplicative Inverse
6) Additive Inverse
7) Reversal
8) Substitution
