Answer:
D inverse property
Step-by-step explanation:
x=1+2i
y=-1-2i
Both x and y are complex numbers with both real and imaginary parts.
x+y = (1+2i) + (-1-2i)
= 1 + 2i - 1 - 2i
= (1 - 1) + (2i-2i)
= 0 + 0 = 0
Since the two given complex numbers add up to 0, this means that each number is the additive inverse of the other.
So x is the inverse of y and y is the inverse of x.
Among the given options, option D , namely, inverse property is the correct one.
