Math Assessment Macroeconomic Principles Spring 2010 January 24, 2010. This assessment will not be graded but I want everyone to work on it and turn it in this week. That will give me an idea of the level of math of the class on an average, and will also provide me inputs on what needs to be done. Note that you are to plot the graphs by hand, and not use a calculator or computer. 1. Plot the following lines on a graph paper. (a) y = 3 x + 10. (b) y = 2 x . (c) y = 5. (d) y = 15 - 2 x . (e) y = 30 -

Unformatted text preview: x . 2. Solve the following set of equations. (a) y = 3 x + 10 and y = 15-2 x . (b) y = 2 x and y = 15-2 x . (c) y = 5 and y = 15-2 x . (d) y = 3 x + 10 and y = 30-x . (e) y = 2 x and y = 30-x . 3. If x , y , and z are three variables such that x + y = 1, and z = 1 1-x , then nd y , and z when (a) x = 0 . 2, (b) x = 0 . 25, (c) x = 0 . 4, (d) x = 0 . 6, (e) x = 0 . 8. Make sure that you show all steps in the calculations. 1...
