Answer:
Step-by-step explanation:
This is just a big multiplication, but it gets more simple when you break it into steps.
First consider 
. This multiplies out to 
Next, 
. This is 
Finally, 
. This is 
Sum these three expressions together and you get
The solution is x = 9, -11
Answer: B x - 3y = 11 and y = -3x + 23
Explanation:
Two lines that are perpendicular have slopes that are negative reciprocals, meaning if there are lines that have slope of 2 or 2/3 or -5, lines that are perpendicular have slopes of -1/2, -3/2, 1/5 respectively.
For this question, you must make each equation in terms of y (isolate y)
A: you get -5/2x -(9/2) = y and y = -5/2x + 27/2. Here, -5/2 = -5/2 so this can’t be it. We’re looking for negative reciprocals
B: you get y = 1/3x - 11/3 = y and y = -3x + 23.
1/3 and -3 are negative reciprocals of one another so this is your answer.
