Compound Inequalities - Special Cases

Here is a quick reteaching video that may clear up some questions on the SPECIAL CASE problems such as NO SOLUTION  and ALL REAL NUMBERS. 

Remember that it is possible that OR compound inequalities or GREATOR absolute value inequalities may produce a solution of ALL REAL NUMBERS.

Remember that it is possible that AND compound inequalities of Less ThAND absolute value inequalities may produce a solution of NO SOLUTION. 

UNIT #4 TEST --- OVER CHAPTER 6

There will be a test over Unit #4 which covers material from Chapter 6 in our text.   The main topic covered is inequalities with one section on absolute value inequalities.  A great way to review would be to complete the Chapter 6 Pre Test which can be found at this link:

Mr Simpson and Mr Spilker will also be available for extra help before or after school if needed to prepare.   The only exception to this is Wednesday morning because of teacher meetings.  

6.5 Solve and Graph Absolute Value inequalities

Great video that reteaches lesson 6.5   

REMEMBER:   greatOR   and less thAND

Here are some additional notes that also may be helpful:  https://docs.google.com/open?id=0BzJ2Jy-k3iPONEgtTmljWHJ4S00

6.5 Part #1 Solving Absolute Value Equations

Remember to set up two equations to find your TWO solutions to an absolute value equation. 

6.3 Solving and Graphing Compound Inequalities

TIPS for working with compound inequalities:
-Solve the two inequalities that make up the compound inequality seperately, then graph their two solutions together. 

-The AND type grpah will look like a dumbbell
-The OR type graph will look like OARS on a boat

6.2 Solving MultiStep Inequalities

Whenever you solve inequalities be on the lookout for this rule:
When you multiply or divide BOTH sides of an inequality by a negative number you must flip the inequality symbol. 

ALSO KEEP IN MIND THAT INEQUALITIES ARE SOLVED JUST LIKE EQUATIONS.  YOU HAVE THE SAME GOAL OF ISOLATING THE VARIABLE. 

Chapter 6 Section 1 Solving 1 step Inequalities

IMPORTANT REMINDERS:

You solve an inequality just like you solve an equation. 

When graphing with a < or > sign you will always have an open circle because that point is not a solution.  An inequality sign that contains an = will always have a closed circle. 

If your variable is on the left side of your inequality symbol then you can simply shade the direction the arrow points. 

Additional review for mid term assessment

Here is an additional review for the Algebra 1 midterm assessment.  Answers are attached at the end of the document.  The midterm will be taken in 2 parts.  Part 1 will be a short answer part and will be taken on Tuesday.  Thursday's section will be multiple choice.

Statistics - Reading the shape of a distribution

Students:  understand that symmetrical is the same as normal.   Positive is the same as skewed right and negative is the same as skewed left. 

Here is a link to a handout that can help you better understand distribution:
