What is the additive inverse of the expression below, where are a and b real numbers?

2a+b

a. -1
b. 0
c. 2a-b
d. -2a-b

  D. -2a-b

Step-by-step explanation:

The additive inverse is found by multiplying the expression by -1.

  -1(2a+b) = -2a -b . . . . matches selection D

1 is not true because 12x does not have a y in it
2 is true
3 is not true because 12x does not have a y and 24y does not have a x
4 is true
5 is not true because 24y does not have an x in it
6 is true
7 is not true because 24y does not have an x in it
8 is true
