A car dealership sells 20 cars when there is a $2,000 markup over the factory price of each vehicle. The sales department determines that for each $400 decrease in markup an additional 6 cars are sold. Write a function that models the total monthly profit P(n). Let n represent the number of markdowns. A) P(n) = 2400n2 + 4000n + 40,000 B) P(n) = 2400n2 − 4000n + 40,000 C) P(n) = −2400n2 + 4000n + 40,000 D) P(n) = −2400n2 − 4000n + 40,000

30 points!Tina is going for a bike ride. When she leaves her house, she starts pedaling and her speed steadily increases. As she approaches the stop sign at the end of her street, she slows down at a steady pace until she comes to a complete stop. After waiting at the stop sign for her turn to go, she starts pedaling again and her speed steadily increases at a slower pace than when she first left her house. She reaches a comfortable speed and rides at this speed until she approaches another stop sign, causing her to steadily slow down until she again comes to a complete stop. Which graph represents Tina’s bike ride?

Which statements are true about the ordered pair (10, 5) and the system of equations? {2x−5y=−5x+2y=11 Select each correct answer. The ordered pair (10, 5) is a solution to the first equation because it makes the first equation true. The ordered pair (10, 5) is a solution to the second equation because it makes the second equation true. The ordered pair (10, 5) is not a solution to the system because it makes at least one of the equations false. The ordered pair (10, 5) is a solution to the system because it makes both equations true.
