calculate the acceleration of a bus whose speed changes from 9 m/s to 14 m/s over a period of 5 s. Remember: Acceleration=final speed- initial speed÷time

Step-by-step explanation:

Acceleration=(final speed-initial speed)/time

First, write out the information you have already been given.

Acceleration: ?

final speed: 14m/s

initial speed: 9m/s

time: 5 seconds

Next, write the numbes where they fir in the formua for calculating acceleration.

Then, subtract the numerator values and simplify the whole equation.

This means the acceleration of this particular bus is:

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
