Which property of addition is shown below? if x = a + bi and y = –a – bi, x + y = 0. a. commutative property b. identity property c. associative property d. inverse property thinking a?

The answer is inverse property of addition.

Step-by-step explanation:

Given x = a + bi and y = –a – bi,

we have to tell the property if x+y=0

As x+y=a + bi+(-a - bi)=0

Inverse property of addition states that if any number real or complex add to its opposite equals to zero.

Here, the complex number a and y adds up to 0

x+y=0

⇒ They shows inverse property of addition.
