Can anyone help with attached document? Thanks in advance

1. For the equation graphed at left: a. Determine the line's slope m: m = _____________ b. Determine the line's y - intercept: _____________ c. State the equation algebraically in slope - intercept form: ________________________________ 2. & 3. Solve for the variable. Check your answer in the original equation, if you determine the equation has a single solution. For full credit, please show all work, including check step! 2. 6 ( 5 x11 )=12 ( 2 x+5 )+18 ____________________ 3. 2 3 y+3= ( y +8 ) 4 3 4 ____________________ 4. Solve the linear inequality. Write the solution set and graph it on a number line. If you are typing the quiz, you can easily create a number line and graph inequalities using your keyboard. \"How-to\" link is in Content > Course Resources > Webliography in our LEO classroom. 2 ___________________ 9. As chief financial officer at Amalgamated Pharmaceutical, you track costs and revenue for the daily manufacturing process for your company's top-selling product, Shovitall, the drug that relieves math anxiety. Daily production costs $6,300 plus $45 for every case produced. Daily revenue coming in equates to $115 per case sold. a. Determine the cost (C) and revenue (R) equations for this manufacturing process. Let x represent number of cases. Cost equation: ___________________________________ Revenue equation: ___________________________________ b. How many cases must be sold each day for this manufacturing process to break even? Your answer must be supported either algebraically or graphically - don't just give an answer! Number of cases sold daily to break even: _________________________ 10. The following table lists the amount of money Americans spent on antipsychotic drugs annually from 2004 to 2011 [Source: IMS Institute for Healthcare Informatics, "Use of Medicines in the United States: Review of 2011"] Years After 2004 (x-value) 0 1 2 3 4 5 6 7 Billions of Dollars Spent on Antipsychotic Drugs per year (y-value) 8.6 9.9 11.4 12.8 14.3 14.7 16.1 18.2 a. Draw a scatterplot of the data, AND then graph the linear model equation on the same graph the scatterplot is on. You may graph on graphing paper and scan it, or graph using a calculator and attach an image of the screen, or you may use spreadsheet software and attach the file (free online graphing calculators, tutorials for TI-80 series graphing calculators, and an instructional video on how to build scatterplots and find the linear regression model's equation using Excel are all available in our LEO classroom at Content > Course Resources > Webliography) b. The linear regression model of this data produces an equation defined as: y=1.3048 x+ 8.6833 where x represents the number of years after 2004. Use it to predict the annual amount (in billions of dollars) that will be spent in the US on antipsychotic drugs in the year 2024 (round answer to nearest tenth of a billion dollars). Hint: how many years since 2004 is 2024? Predicted 2024 amount spent ($US billions): ____________________
