Answer:
1. her elevation at noon was 3 meters
2. (-2, 7)
3. (1, 0)
Step-by-step explanation:
1. when x = 0, it is noon, y = 3 when x is 7
2. when x = -2 it is 10 am because when x is 0, it is noon, or 12 pm, her elevation is 7 meters above sea level
3. when x is 1, it is 1 pm, and her elevation is 0 meters
ok so i can’t answer all of them BUT!! if a=a: infinitely many, x=a: one solution, a=k: zero solutions. hope this helps!
