George and chin work as landscapers. george charges $90 for a 6-hour job. chin charges $84 for the same job. the table shows their price structures. an equation representing george’s charges is written in the chart. landscaping cost george chin george charges one hourly rate for the first three hours and then reduces his rate for additional hours. chin charges the same initial rate as george for the first two hours and the same reduced rate for additional hours. mc016-1.jpg what is the equation for chin’s charges needed to solve the system and find the cost of the initial and additional hours?

C. 2x + 4y = 84.

C

Step-by-step explanation:

did the test

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.

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
