15. Table

What does this word mean to you?

This word actually means…..an arrangement of words, numbers, or signs, in columns, to show a set of facts or relations..

Examples… Explain how you would use this word in math.

Lesson

7. EE.4b. Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific

rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem

Inequalities An inequality says that two values are not equal. 

a ≠ b says that a is not equal to b

There are other special symbols that show in what way things are not equal.

a < b says that a is less than ba > b says that a is greater than b(those two are known as strict inequality) 

a ≤ b means that a is less than or equal to ba ≥ b means that a is greater than or equal to b.

Thursday: Bell Work

Write an inequality to model the situations.

Inequalities

Reminder note: When dividing or multiplying by a negative, switch the inequality symbol.

- 12 x < 24

÷ -12 ÷ -12 divide by -12

x > -2 symbol flips because of the symbol
