Math Problem Statement
Solution
Let's analyze and solve the matching problem step-by-step.
You have a set of inequalities that need to be matched with corresponding number lines. I'll first solve each inequality, then determine the number line that corresponds to each solution.
Equations and Inequalities:
-
or :
-
For : (one inequality is )
-
For : (the other inequality is ).
Therefore, the solution to this inequality is or , which suggests two disjoint intervals on the number line. This matches number line D, showing two separate sections of solutions on either side.
-
-
or :
- For :
- For :
So the solutions are and . This matches number line C, which has dots at and indicating these points.
-
:
-
Simplify: This means either or .
- For :
- For :
So the solution is or . This matches number line A, with points at and .
-
-
:
- Divide the inequality into two parts:
So the solution is . This matches number line E, with an open interval between and 2.
-
:
- Solve for :
So the solution is . This matches number line B, which shows all values less than or equal to 12.
Final Matching:
- D: or
- C: or
- A:
- E:
- B:
Let me know if you want more details on any step! Here are five related questions for further practice:
- How do you solve compound inequalities involving "or" and "and" conditions?
- How do you graph inequalities on a number line?
- What are absolute value equations and how do they affect solution sets?
- How do you handle equations with fractions?
- How do you know when to reverse inequality signs?
Tip: When solving compound inequalities, treat each part separately before combining them according to the conditions (e.g., "or" means union, "and" means intersection).
