Question

Indicate which property is illustrated in Step 4.

Step 1 12 - 5x - 12 + 6x = (12 - 5x) + (-12 + 6x)
Step 2 = (12 - 5x) + (6x - 12)
Step 3 = 12 + (-5x + 6x) - 12
Step 4 = 12 + (-5 + 6)x - 12
Step 5 = 12 + x - 12
Step 6 = x + 12 - 12
Step 7 = x + 0
Step 8 = x

Answer 4

We did this one already. It should look familiar?

Answer 5

comm again @SACAPUNTAS

Answer 6

I'm here!

Answer 7

i was asking if it commutative

Answer 8

Oh! No. Distributive. That's the one that lets you say:
\(ac + bc = (a + b)c\)

Answer 9

Indicate which property is illustrated in Step 4.

Step 1 12 + 11x - 12 - 2x + 5 = 12 + (11x - 12) - 2x + 5
Step 2 = 12 + (-12 + 11x) - 2x + 5
Step 3 = [12 + (-12)] + (11x - 2x) + 5
Step 4 = 0 + (11x - 2x) + 5
Step 5 = (11x - 2x) + 5
Step 6 = (11 - 2)x + 5
Step 7 = 9x + 5

associative
additive identity

additive inverse

Answer 10

Ok, do you know what property says \(a + -a = 0\)?

Answer 11

ummmmmm inverse

Answer 12

Yes, got it.
