Elijah gets paid $15.50 per hour in addition to a weekly salary of $50. this week he wants to earn more than $400. how many hours will he need to work?

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.

easy math just plug in a and b

step-by-step explanation:
