Bell Ringer 81715 Solve the following equation 1
Bell Ringer: 8/17/15 Solve the following equation:
1 -3 and 1 -4 Solving Multi. Step Equations Learning Target: I can solve linear equation, with absolute value and apply to the real world.
Recall: Multi-Step Equations: Steps to solving: Use Distributive property to get rid of parentheses Combine like terms on each side of equals sign “Move” variables to left of equals sign by adding or subtracting “Move” constants to right of equals sign by adding or subtracting Get variable by itself by either dividing or taking the root.
Examples:
Solving Equations with Absolute Value What is the definition of absolute value? In order to solve equations with absolute value, you must isolate the expression with absolute value first. Then you apply the definition of absolute value to solve the equation. Challenge ? : At most, how many solutions are in an absolute value equation?

Bell Ringer: 8/18/15 Write an algebraic expression for the following: The difference between the product of four and a number and six
Assignment pg. 22 -23 #24, 36, 39, 41, 43 pg. 30 #15, 22, 25, 28, 33
Learning Target: I can solve simple inequalities and apply them to real world situations. Sec 1 -5: Inequalities
Inequalities: These are solved in the same way as equations, however, if you multiply or divide by a negative value, the inequality symbol reverses.
Inequalities: Words: Symbols: Greater than > Less than < Greater than or equal ≥ to Less than or equal to ≤
Inequalities: Words: On the number line: Greater than >, open circle, shade Less than Greater than or equal to Less than or equal to right <, open circle, shade left ≥, closed circle, shade right ≤, closed circle, shade left

Learning Target: I can solve compound inequalities, including those with absolute value and apply them to real world situations. Sec 1 -6: Compound Inequalities
Compound Inequalities: Defined as two inequalities joined by the word “and” or the word “or. ” In order to solve a compound inequality you must solve each part of the inequality. Generally, “and” compound inequalities have the algebraic expression in between two values with < or ≤ ; “or” statements use one of each inequality symbol.
