Write an equation of the line that passes through (18, 2) and is parallel to the line 3y - x = -12.
Alona [7]

Answer:

3y=x-12

y=x/3-4

m=1/3

At (18,2)

y-2=1/3(x-18)

y-2=x/3 - 6

y=x/3 - 4

A car going 72.0 km/h (20.0 m/s) slows down to 36.0 km/h (10.0 m/s) in 5.00 seconds. Calculate the acceleration in
Vlada [557]

Answer:

-2 m/s^2

Step-by-step explanation:

Just as you would calculate the velocity when a body moves from point A to point B in a time T, we are going to calculate the acceleration as the difference of the velocities (final - initial) and divide it by the time it took:

Velocity_final = 10 m/s

Velocity_initial = 20 m/s

Time = 5 s

acceleration = (Velocity_final -  Velocity_inital)/Time

                     = (10 m/s - 20 m/s)/5 s

                     = (-10 m/s) / 5s

                     = -2 m/s^2

The acceleration in m/s^2 is -2

Answer:

slope is 3

Step-by-step explanation:

Slope = \frac{change  in  y }{change  in  x }

change in y = (13-7),  (19-13),  (25-19),  (31-25)

change in y = 6

Change in x = (4-2),  (6-4),  (8-6),  (10-8)

Change in x = 2

Therefore slope = \frac{6}{2}

Slope = 3
