Systems of Equations (Part I) Answer the question and solve the problems below. Make sure you show all your work so you can get partial credit even if you get the final answer wrong. Best Rentals charges a daily fee plus a mileage fee for renting its cars. Barney was charged $123.00 for 3 days and 300 miles, while Mary was charged $216.00 for 5 days and 600 miles. What does Best

Use the variables X and Y to represent the values of shares of Company X and Company Y. 2000X + 10000Y = 340,000 8000X + 6000 Y = 340,000 Solve for the value of a share of Company X and Company Y. Show your work. 2000x = 340,000 -- 10000y x = 170 -- 5y 8000 (170 -- 5y) + 6000y = 340,000 1,360,000 -- 40,000y + 6000y = 340,000 -34,000y = -1020000 y = 30 2000x + 300000

linear equation and a linear inequality be solved in the same way? Explain why. What makes them different? Team B A linear equation and a linear inequality can be solved the same except for very specific scenarios: one flips the inequality sign whenever multiplying or dividing by a negative (Staples, 2012). What makes them different is that the answer will not be a single number, but a range of numbers. Stapel,

Demand Management Plan for Wild Dog Coffee Company:Impact of Advertising on Product DemandTo analyze the impact of advertising on product demand, a simple linear regression model to forecast the pounds of espresso beans used each month based on advertising expenditures can be used. The model used can be found in the Appendix to this paper.The regression equation is: Y = 542.78 + 0.42X where Y is the pounds of espresso

The report develops mathematical model and Excel is ideal spreadsheet to implement a mathematical model because it is developed to carry out a number of iteration. The report uses the spreadsheet to determine the time that the engine takes to reach 3000 rpm with continuous 100% fuel input. The Table 1 provides the layout of the spreadsheet, which reveals the time on the first row and the system variables on
