Simplify watching "-" and Substitution

Image
 Things that probably need reviewing: Be careful of "-" NEGATIVE   or   SUBTRACT   or OPPOSITE OF (...) The Video Below focuses on when we use OPPOSITE  OF  for "-" ***************************** ***************************** ***************************** ***************************** ***************************** ***************************** ***************************** ******************************************** DIVISION becomes MULTIPLY by the RECIPROCAL ****************************************** ************************************* ************************************* *************************************

Solve and Graph inequalities and Absolute Value

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 *******************************************...
