Answer:
Step-by-step explanation:
The formula of a slope:
We have two points (3, 1) and (5, 8).
Substitute:
34 feet / (1/8) feet
(1/8) = .125
34 / .125 = 272
Since you can only perform addition and subtraction on variables that have the same variable following them, the correct answer is B. 3 - 2i.
Here's why:
1 + 2 + (3i - 5i) =
3 - 2i
