Inequalities Assignment #1

Due 5/29/20

Writing and Graphing Inequalities YouTube video

Remember: IN = NOT, therefore Inequality means NOT equal, NO EQUAL sign

Inequality symbols:

< Less than > Greater than

¡Ü Less than OR equal to

¡Ý 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 ¡Ý 6

7.) 18

x ¡Ü 10

GRAPHING Inequalities

closed circle DOES include the number, ¡Ü or ¡Ý

PRACTICE PROBLEMS

Graph the inequality on a number line.

8.) a < 4

9.) f ¡Ü 7

10.) n > 0
