REVISITING the PEMDAS You may want to print the jpg below before you watch the video... This Video show how to UNDO the process so we can ISOLATE the X to SOLVE an EQUATION ******************************************* Understanding the INEQUALITY Graphing an Open Sentence that is an INEQUALITY. (Marking all NUMBERS that will MAKE the INEQUALITY TRUE .) For example: Graph the Solution Set for " 5 < x " " the > or < will NOT ALWAYS point in the direction of the shaded solution. SINCE "5 < x" is EQUIVALENT TO " x > 5 " the graph is ... By READing the inequality starting with "X". " 5 < x " would be read "X is GREATER than 5." Since we are graphing "X's" , this method of translation will lead to the correct direction of the ARROW in the graph. OR TESTING A FEW NUMBES Back into the ORIGINAL PROBLEM to be sure that they MAKE IT TRUE *******************************************...
