Add and completely simplify the expression 813+2-243{“version”:”1.1″,”math”:”813+2-243″} Read the following information and enter the exact answer in radical form in the box below. You may record your response in any of several ways.  You may use the templates found by selecting the “+” sign, then Equation, then Graphical Equation to enter your answer in nice mathematical notation.  Use of this tool is intuitive, but it is not required.  If you use the Equation tool, make sure your response looks exactly like you intend it to look. You may instead type a verbal description of your answer.  As an example, to describe the answer -2xy{“version”:”1.1″,”math”:”-2xy”}, you could type “the negative square root of 2xy, where 2, x, and y are all under the square root.”  A third option is to record yourself saying your final, simplified answer using the Record Audio button.  I do not know how recording audio or video or uploading a picture of your written solution will work with Honorlock, but you may try them if you want to.  Feel free to use more than one of these entry methods.  Bottom line: clearly communicate your response so that it can be understood and manually scored by the instructor.

Use your graphing calculator or the online application at www.desmos.com to graph the equation y=1x + 1-1×2 – 1{“version”:”1.1″,”math”:”y=1x + 1-1×2 - 1″} Enter the x{“version”:”1.1″,”math”:”x”}-intercept (or x{“version”:”1.1″,”math”:”x”}-intercepts if more than one) of the graph.

The domain of the expression 4-2x{“version”:”1.1″,”math”:”4-2x”} is the set of all real numbers _______ the real number _______ .  [In the first box, enter less than, greater than, less than or equal to, or greater than or equal to.  In the second box, enter a real number that correctly completes the statement.]

Solve the equation and enter the solution.  If there is no solution, enter NO SOLUTION. 2x – 13 + x=74{“version”:”1.1″,”math”:”2x - 13 + x=74″}
