Which demonstrates the commutative property? * O a+b=b+a
O (a + b) + c = a + (b + c)
O a(b + c) = ab + ac
O a+0= a

Commutative property; No matter how you arrange the sums you'll get the same answer.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
