42) according to the 2000 census the population of canton was 7,720. holly spring's population was 3,200. canton's population increases at a rate of 80 people a year and holly spring's population increases by 120 people a year. which equation may be used to determine the number of years before the populations are equal?

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.

can i see the following ?
