Answer:
5. C
6. A
Step-by-step explanation:
To find the answer, plug in the x- and y-values into each equation. When the equation comes to be true that is your answer.
So for question 5, you plug -5 into the x and 13 into the y for each equation. The first equation will give you an answer of 13 = -7, which isn't true.
The second will give you 13 = 7, so you keep going.
The third gives you 13 = 13, which is true, so that one must be the answer.
Do this for every question and it will give you the answer.
Answer:
Speed = 0.1333 km/minute
Step-by-step explanation:
According to the graph :
At 10 minutes, it could be observed that the Distance moved started to reduce until distance moved reached 0 at 20 minutes. This could be interpreted as a case of negative acceleration (that is deceleration) whereby the distance covered started to decrease with time until the it rest at 0.
Speed during the last 30 minutes :
Speed = distance / time
Distance moved during this period :
Distance (from 0 to 4km)
Time = (from 30 to 60 minutes)
Speed = (4 - 0) / (60 - 30)
Speed = 4 / 30
Speed = 0.13333 km per minute
