2(P + 1) > 7 + P
2P + 2 > 7 + P
2P - P > 7 - 2
P > 5
Using function concepts, it is found that the turning points of the graph are:
- November 2000, when it goes from increasing to decreasing.
- December 2000, when it goes from decreasing to increasing.
- June 2001, when it goes from increasing to decreasing.
In a graph:
- A function is increasing if it is <u>pointing upwards.</u>
- If it is <u>pointing downwards,</u> it is decreasing.
- A turning point is when the function changes from <u>decreasing to increasing or vice-versa</u>.
In this problem:
- Initially, the function is increasing.
- In month 3, that is, November 2000, it starts to decrease, thus, in November 2000, we have a<u> turning point.</u>
- The next month, that is, December 2000, it starts to increase again, so it is another <u>turning point</u>.
- It increases until month 9, which is June 2001, when it starts to decrease, being the <u>final turning point.</u>

Answer: 24 min
Step-by-step explanation:
2 hrs / 5 carts = 120 min / 5 carts
120 / 5 = 24 min / 1 cart
21. 0.25x - 1.25 - 3x + 2 = -2.75x + 0.75
22. 15/100= 0.15. 0.15•64,000= 9,600. The answer is D.
23. 1,200-300= 9,000. 1,200+300= 15,000. 9,000/15,000= 3/5. 3/5= 0.6. 60% of the building is aboveground.
24. The patterson seems to be the y=18x and when you plug 7 in to the equation, you get 126, not 128, so D is the answer.
