A bird flies down from a higher elevation to a lower elevation at a rate of 2 meters per second Which equation models the bird's change in elevation, in meters, after 30 seconds?
A.{-30)(-2)=-60
B.30(-2)=-60
C.30(-2)=60
D.30.2=60

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
