Question

2. A bird starts at 10 meters and changes -6 meters.

b) Explain how you know the final elevation of the bird will be positive.

c) What is the final elevation of the bird?

Answer 1

I know the final elevation of the bird will be positive because 10 - 6 is positive. It also wouldn't make sense for the bird to end up below the ground.

The final elevation of the bird is 4 meters.
