Aboat rental company charges a fee per hour. the charge is the same per hour . the ordered pairs(2,14.50) and (5,36.25) represent the corresponding hours, x,and the cost, y. what is the rate of change expressed as a unit rate?

One hour costs 7.25 $

Step-by-step explanation:

The charge for 2 hours is 14.50 $, then 14.50 $ / 2 hours = 7.25 $ / hour

The charge for 5 hours is 36.25 $, then 36.25 $ / 5 hours = 7.25 $ / hour

One hour costs 7.25 $

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.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
