Think of it as -5+1i/2i, since 1i=i. From there, the i's could cancel out since dividing a number by itself would just equal 1. It would then be -5+1/2 which would be simplified to -4 1/2. No need to worry about those i's at all!
Answer:
Step-by-step explanation:
(0, -9) and (3,3)
(3+9)/(3-0) = 12/3 = 4
y + 9 = 4(x - 0)
y + 9 = 4x - 0
y = 4x - 9
11x - 3 = 5x + 11
11x - 5x = 11+3
6x = 14
x = 14/6 =7/3
8 is the answer to your question
120 + 120 + X + X = 360
240 + 2X = 360
2X = 120
X = 60
