Inequalities Assignment #1 Writing and Graphing Inequalities YouTube video Remember: IN = NOT, therefore In equality means NOT equal, NO EQUAL sign Inequality symbols: < Less than > Greater than Less than OR equal to ≤ Greater than OR equal to ≥ PRACTICE PROBLEMS: Write the word sentence as an inequality.

1.) A number n is greater than 1

2.) Twice the number p is fewer than 7

3.) A number w minus 3 is less than or equal to 10

4.)A number z is divided by 2 is at least -6

Remember: A solution set is more than one answer, it is all the answers that work in the inequality. SUBSTITUTE the answer to see if it works (plug-n-chug the answer) PRACTICE PROBLEMS: Tell whether 3 is a solution for the inequality. Yes or no?

5.) B + 4 < 6 6.) 9 - n 6 ≥ 7.) 18 x 10 ≤

GRAPHING Inequalities Remember: open circle does NOT include the number, < or >

closed circle DOES include the number, or ≤ ≥ PRACTICE PROBLEMS Graph the inequality on a number line. 8.) a < 4 9.) f 7 ≤ 10.) n > 0 11.) p -3 ≥ Write and graph an inequality for the situation: 12.) A cruise ship can carry at most 3500 passengers. 13.) A board game is designed for ages 12 and up.


Inequalities Assignment #2 - Solving Inequalities Using Addition and Subtraction YouTube Video REMEMBER: Whatever you do to one side, you do to the other, just like solving equations PRACTICE PROBLEMS: Solve the inequality. Graph the solution.
