Use a geometric representation to determine the sum of the complex numbers. z1= -2 - 6i z2 = 5 + 9i z = 3 + 3i z = -3 - 3i z = 3 - 3i z = -3 + 3i

The first answer ⇒ 3 + 3i

Step-by-step explanation:

∵ Z1 = -2 - 6i ⇒ red point

∵ Z2 = 5 + 9i ⇒ blue point

∴ Z = 3 + 3i ⇒ green point

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

answer: i guess 5 units?
