Question 767725: compound inequalities
I really need someone to work this one out with all the steps so I can understand the next problems I must do that are like it. I would appreciate so much if someone could help me.
-12 < 12 + 4x < 0 my "and"
12 – x > 15 or 7x – 13 > 1 my "or"
being careful of how a negative x-term is handled in the solving process. Show all math work arriving at the solutions. Show the solution sets written algebraically and as a union or intersection of intervals. Describe in words what the solution sets mean, and then display a simple line graph for each solution while using the following words in your work:
Compound inequalities, And, Or, intersection, and Union.

Words: can be any real number that is between the values minus 6 and minus 3, not including minus 6 or minus 3.

Draw a number line. Put a little circle on the -6 and another little circle on the -3. Make a heavy line between the two little circles.
