Answer:

A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.

Step-by-step explanation:

By definition, Acceleration is the rate of change of Velocity of an object.

I.e it is the( final velocity minus initial velocity ) ÷  by the time it took for the velocity to change.

If we observe the choices only one choice gives us all 3 components (final velocity, initial velocity, time taken for velocity to change), which is :

A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.

2x – 3y = -5
vampirchik [111]

Answer:

y = 3

Step-by-step explanation:

2x-3y = -5 --------- (1)

y = 2+x ------- (2)

substitute (2) into (1)

2x-3y = -5

2x-3( 2+x ) = -5

2x-6-x = -5

2x-x = -5+6

x = 1

substitute x = 1 into (2)

y = 2+x

y = 2+1

y = 3

maksim [4K]
The negative in front of the second bracket means that it's times by -1 so each of their signs switches: 
3m^2+2n-m^2-2n 
Add like terms 
2m^2 
the 2n cancels out
