How can we show a number increased by 2? can you prove this using a model? if so, draw the model.

x + 2

Step-by-step explanation:

Let x be the unknown number,

For making the diagram to model this problem,

Take a grid that shows x, ( shown below )

Then take a grid that shows 2.

Join these grids,

We obtain a grid, showing x + 2

Hence, the required expression that represents the given situation is x + 2

the distance between point a and point b is 6 units

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
