Need the answer please Today, we use algebraic tools such as writing and solving equations, Systems of equations, Inequalities, and systems of inequalities to help us Measure and interpret real-world scenarios. What twenty-first century tasks do these tools help us manage?

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.
