Answer:
Step-by-step explanation:
1. y = -2x + 7
2. Graph it (Mark (0, 7) or 7 on the y axis and go over one, down two, mark it and draw a line through both)
3. -2y = -x + 6
4. divide entire equation by 2 to isolate y
5. -y = -x + 3
6. multiply entire equation by -1 to make it positive
7. y=x+3
8. graph it (Mark (0,3) and go over one, down one, mark it and draw a line through both new points)
9. Where the lines intersect is your answer
Answer: 7 x 3 = 21

15 B
16 C
17 A
Step-by-step explanation:
The equations will only have one solution because they have different slopes and also next time use desmos for those kinds of problems it’ll always help
To prove this statement, start with a picture of alternate interior angles that are assumed to be congruent, but don't assume the lines are parallel. In the picture below, assume . Prove that (two parallel bars indicate parallel lines). If corresponding angles are congruentthen lines are parallel.
