It's an acute angle because it's smaller than 90 degrees and isn't a straight line.
I think it’s B and C. They are the same distance away from 0 but, they are on different sides. Therefore, they are opposites.
Answer:
2x + 4y = 12 and y = -1/2x + 3
Step-by-step explanation:
3x + 2y = 9
- (3x + y = 6)
=> y = 3.
Therefore 3x + (3) = 6, 3x = 3, x = 1.
The solutions are x = 1 and y = 3.
