Example: Solving Inequalities (Multi-Step) Solve the following inequalities and graph the solution on the number line. 2y + 3 < 9 b. 3y + 2y > 15. Step 1: Opposite of add is subtract Step 1: Add like terms. So subtract 3 from both sides So add 3y + 2y. Step 2: Perform the necessary operation Step 2: Perform the necessary operation

An iterative loop becomes non-loop if the step has the wrong sign. The program looks at first, last and step and says “Wrong” and does not execute the loop at all. In other words, the calculator is too smart to get into an invalid loop. Pre-Test Loops ask the “do I do this loop” question before executing another trip through the loop.

We include instructions for this step as well. Although not used in the analysis, the data set also includes two identification variables [student ID (STU_ID) and school ID (SCH_ID)] and one weight variable (F2PNWLWT). Copies of the data set and output are available on the companion website. The data set file is entitled, “REGRESSION.SAV”.
