The range of all real numbers x such that 2x − 5 < 7 or 4x + 10 > 6 is a. (-1,6) b. (-infinity, infinity) c. an empty set d. (6,-1)

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.
