A: Deena subtracted 25, instead of adding it.
B: 9x - 25 = 88.
C: no idea
Answer:
I agree with all of them
Step-by-step explanation:
they are all connected mathematically (I used 3.14 I hope that the right idea)
The answer:
<span>the average rate of change for the first 50 seconds:
it is v= 100 m/ 50 s = 2 m/s
</span><span>Thomas speed is 2 m in each second for the first 50 seconds.
</span><span>The average rate of change for the 70 remaining seconds:
the time is between [70; 120]
so the distance is d= 200m - 40m= 160m
the average rate is
v= 160m / 70 s = 2 . 28m /s
</span>
Y = -1/2x + 5 is the answer
