X + y = 19
x - y = -7
Subtract both
2y = 26, y = 13
Plug into first equation
x + 13 = 19
x = 6
Solution: x = 6, y = 13

Answer:
16 +88i
Step-by-step explanation:
8 x (11i + 2 ) =
Distribute
8*11i + 8*2
88i +16
Writing in the proper form
16 +88i
42 (1- 25/100) = 63/2 = 31.5 dollars
answer is $31.50

Answer:
Step-by-step explanation:
If you move down 1 unit, you simply subtract 9 units from the given equation.
g(x) = 4x^2 - 16 - 1
g(x) = 4x^2 - 17
Shifting right is a little bit tricky. To shift right, you have to do the opposite of what you would do on the number line. The x has to become x - 9 because the x value (you will learn later) is part of a distance and distances always subtract one from the other.
The wrong way to do it is in answer A.
B is the correct answer
h(x) = 4(x - 9)^2 - 17
