(5 + i)(4 - 2i)
20 - 10i + 4i - 2i²
20 - 6i - 2(-1)
20 - 6i + 2
20 + 2 - 6i
22 - 6i
Answer:
(6,5)
Step-by-step explanation:
When reflected across the x axis, x-values does not change, and y-value changes on opposite.
(6, -5) ---> (6, 5)
V=3/4
Multiply 3/8 by 2 to get the V alone
M-5/8 = -1/4
Add 5/8 to both sides:
M = -1/4 + 5/8
Rewrite the fractions to have a common denominator
-1/4 = -2/8
Now you have m = -2/8 + 5/8
M = 3/8
C.
-2(4-1)
Distributing: (-8 +2) = -6
