Answer:
20 + 0i
Step-by-step explanation:
(10 + 5i) + (10 - 5i) = 20 + 0i
Answer:
B.(-5,-7)
Step-by-step explanation:
According to the rule of rotation if you were to have a 270* clockwise you would first switch the x and y values. Ex: (-7,5) -> (5,-7). next you would make the original y coordinate a negative. (5,-7) -> (-5,-7).
