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

A
B
C
D

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

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

if you was gonna solve for a, a is a   < -12
