Answer:
-3(a-b) < 0. divide both sides by -3 and reverse the inequality sign: 0 0
Step-by-step explanation:
If d = rt, Then r = d/t
avg speed = 720/t
Therefore after subtracting penalty points, the function for score is:
![s = \frac{720}{t} - p](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B720%7D%7Bt%7D%20-%20p)
For part 2 i will attach a picture.
Part 3)
Set s = 3 and solve for t
![\frac{720}{t} - 2 = 3](https://tex.z-dn.net/?f=%5Cfrac%7B720%7D%7Bt%7D%20-%202%20%3D%203)
![720 = 5t](https://tex.z-dn.net/?f=720%20%3D%205t)
