Suppose z1 = 7 - 3i and Z2 = 3 – 5i. Which letter
represents the sum z1+ z2?
A
B
C
D

Answer:
point C
Step-by-step explanation:
Given: z1 = 7 - 3i and Z2 = 3 – 5i
Add the numbers with numbers and i's with i's
z1: 7 - 3i
z2: 3 - 5i
z1+z2 = 10 - 8i
the x-axis is the real number and y-axis is the imaginary numbers.
point C is at the -8i and positive 10
