1- Associative property of addition: E
-1+(4+9)=(-1+4)+9
2- Commutative property of multiplication: A
(-9)(0)=(0)(-9)
3- Commutative property of addition: D
-9+1=1+(-9)
4- Identity property of addition: B
-9+0=-9
5- Identity property of multiplication: F
(-9)(1)=-9
6- Associative property of multiplication: C

Step-by-step explanation:
E
To find percent error it's the absolute value of
Actual-Experimental divided by The actual times 100
1) 6-5.43
2) 0.57/6
3) 0.095x100
4)9.5%
That's unusual: repetition: -1/2 - 1/2.
Did you perhaps mean "Factor -1/2 out of (-1/2)x + 6?
Let's do that. Let's rewrite 6 as (-1/2)(-12).
Then (-1/2)x + 6 (-1/2)x -(1/2)(-12)
-------------- = ------------------------ = x - 1/2
-1/2 -1/2
