Question 13 of 47 What is the sum of the complex numbers below?

(5-8i) + (1-11i)

a. 6+19i
b. -6+19i
c. -6-19i
d. 6-19i​

d. 6-19i

Step-by-step explanation:

(5-8i)+(1-11i)

Step 1: Combine like terms within the parenthesis. There are no like terms within the parenthesis. So, drop the parenthesis and move on to the next step.

(Remember!! If you would have had a negative sign in front of either parenthesis, you would need to distribute out the negative sign).

5 - 8i + 1 - 11i

Step 2: Now add like terms.

5 + 1 - 8i - 11i

6 - 19i

You can't combine any more like terms, so this is your final answer.

6 - 19i

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
