You decide to purchase a brand new boat for $20,000. You sell it 7 years later for its worth of $7500. Assuming the boat's value depreciates linearly, how much was it worth 4.5 years after you bought it? It is worth S (Round answer to nearest dollar.)
A survey was distributed to a group of people asking them how many times they had ordered takeout in the past week. They were also asked how much money they saved that week. The scatter plot displays the relationship between the data collected. the trend line goes through the points (1,230) and (3,190). What is the equation of the trend line. The equation should be in slope form. interpret the slope and y intercept in this context. predict the amount of money a person save when they order takeout 9 times.

Degrees Earned The number of postsecondarydegrees earned, in thousands (including associate’s,bachelor’s, master’s, first professional, and doctoral degrees), can be modeled by y = 3.980x2 -17.597x + 2180.899, where x is the number of yearsafter 1990. If this model is accurate, during what yearsfrom 1990 on would the number of postsecondarydegrees earned be less than 3500 thousand?
Aviation The Federal Aviation Administration tracks airline delays for airports around the country. During the first half of 2007, the flights delayed at Dallas-Fort Worth Airport averaged 4,500 per month. Use this information to write an equation in slope-intercept form that could be used to predict the total number of delays throughout the year. Let x equal the month of the year and y equal the cumulative delays.
Suppose that the number of tee shirts sold (N) depends linearly on the price charged (x). Write an equation showing this dependence.
