- Solving one-step and two-step equations
- Understanding and solving inequalities

2. **Systems of Equations**
- Solving systems of linear equations using graphing, substitution, and elimination methods
- Identifying the number of solutions (one solution, no solution, infinitely many solutions)
- Application of systems of equations to real-world problems

3. **Functions**
- Understanding the definition of a function
- Identifying functions from sets of ordered pairs, tables, and graphs
- Understanding function notation and evaluating functions
- Determining if a relation is a function

4. **Patterns and Sequences**
- Identifying arithmetic and geometric sequences
- Finding the nth term of a sequence
- Analyzing and creating patterns

5. **Proportions and Ratios**
- Understanding ratios and proportions
- Solving problems involving proportions
- Applications of percentages in real-world contexts

### Tips for Studying

- **Practice Problems**: Make sure to do plenty of practice problems that cover all related concepts.
- **Use Visual Aids**: Graphs and number lines can help visualize problems, especially with equations and inequalities.
- **Work in Groups**: Discussing problems with classmates can provide different perspectives and help solidify your understanding.
- **Flashcards**: Create flashcards for important terms and concepts.
- **Seek Help**: If there are topics that are still confusing, don’t hesitate to ask a teacher or a peer for clarification.

### Sample Practice Questions

1. Solve for \( x \): \( 3(x - 4) = 2x + 5 \)
2. Graph the equation \( y = -2x + 3 \).
3. Determine if the relation given by the pairs (1, 2), (1, 3), (2, 4) is a function.
4. Solve the system of equations:
\[
\begin{align*}
2x + y &= 10 \\
x - y &= 3
\end{align*}
\]
5. What is the percentage if 25 out of 200 students passed the exam?
