Answer:
Perpendicular
Step-by-step explanation:
A perpendicular line has an opposite slope. one of these has 5x and one has -5x, these are opposite, so they are perpendicular.
Step-by-step Answer:
What is the solution to the system of equations?
y = –3x – 2 ..............(1)
5x + 2y = 15..............(2)
Substitute (1) in (2) to give
5x + 2(-3x-2) = 15
5x-6x-4 = 15
-x-4=15
solve for x:
-4-15 = x
x=-19
Now substitute x=-19 into equation (1)
y = -3x-2 = 57-2 = 55
Therefore the solution is (-19, 55)
Answer:
I believe the first one would be A, and the second would be and 6.25 for the last one. I'm not 100 percent sure, but it's my best guess, I hope it helps, my apologies if it is wrong.
