Abicyclist is going 200m/s. after 10 seconds the bicyclist is going 150m/s. what is his acceleration

Acceleration:  rate of change of velocity with time.

Here, that acceleration is:

100 m/s - 150 m/s

     10 sec

= (-150 m/s) / (10 sec) = - 15 meters per second squared

the answer for this question is 38

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
