2. Solve for x: 2x + 7 = 15

**3. Which inequality represents the graph shown below? (Assume a graph showing a line shaded above the line y = 2x + 1)

a) y < 2x + 1 b) y > 2x + 1 c) y ≤ 2x + 1 d) y ≥ 2x + 1

4. What is the slope of the line that passes through the points (2, 5) and (4, 9)?

a) 1 b) 2 c) 3 d) 4

5. If f(x) = 2x - 3, what is f(4)?

a) 1 b) 5 c) 11 d) -5

6. Solve the system of equations: x + y = 5 and x - y = 1

a) x = 3, y = 2 b) x = 2, y = 3 c) x = 1, y = 4 d) x = 4, y = 1

7. Factor the expression completely: x² - 9

a) (x - 3)(x + 3) b) (x - 9)(x + 1) c) (x - 3)² d) (x + 3)²

8. What is the solution to the inequality: 3x - 6 > 9?

a) x > 1 b) x > 5 c) x < 5 d) x < 1

9. The graph of a quadratic function is a:

10. What is the x-intercept of the line y = 2x + 4?

a) (0, 4) b) (4, 0) c) (-2, 0) d) (0, -2)

Section 2: Answer Key and Detailed Explanations

1. a) x + 6y: Combine like terms: (3x - 2x) + (5y + y) = x + 6y

2. b) x = 4: Subtract 7 from both sides: 2x = 8. Then divide by 2: x = 4

3. b) y > 2x + 1: The shaded region is above the line, indicating a "greater than" inequality. The line itself is not included, so it's a strict inequality ( > ).

4. b) 2: The slope is calculated as (change in y) / (change in x) = (9 - 5) / (4 - 2) = 4 / 2 = 2

5. b) 5: Substitute 4 for x in the function: f(4) = 2(4) - 3 = 8 - 3 = 5

6. a) x = 3, y = 2: Add the two equations together to eliminate y: 2x = 6, so x = 3. Substitute x = 3 into either equation to solve for y: 3 + y = 5, so y = 2.

7. a) (x - 3)(x + 3): This is a difference of squares, factoring to (x - 3)(x + 3).

8. b) x > 5: Add 6 to both sides: 3x > 15. Then divide by 3: x > 5

9. b) Parabola: The graph of a quadratic function (a function of the form ax² + bx + c) is a parabola.

10. c) (-2, 0): To find the x-intercept, set y = 0 and solve for x: 0 = 2x + 4. Subtracting 4 from both sides gives 2x = -4, and dividing by 2 gives x = -2.

Section 3: Key Concepts and Strategies for Success

This section delves into the core algebraic concepts tested on the Florida Algebra EOC. Mastering these areas is crucial for a high score.

1. Linear Equations and Inequalities:

• Solving Equations: Understand the order of operations (PEMDAS/BODMAS) and how to isolate variables using inverse operations (addition/subtraction, multiplication/division). Practice solving equations with fractions, decimals, and variables on both sides.
• Solving Inequalities: Similar to solving equations, but remember that multiplying or dividing by a negative number reverses the inequality sign. Graphing inequalities on a number line is also important.
• Graphing Linear Equations: Learn how to find the slope and y-intercept of a line from its equation (y = mx + b, where m is the slope and b is the y-intercept). Practice graphing lines using different methods (slope-intercept form, point-slope form, using intercepts).
• Systems of Linear Equations: Master techniques like substitution and elimination to solve systems of equations. Understand how to interpret the solutions graphically (intersecting lines, parallel lines, coinciding lines).

2. Functions:

• Function Notation: Understand function notation (f(x), g(x), etc.) and how to evaluate functions for specific input values.
• Domain and Range: Learn to identify the domain (possible input values) and range (possible output values) of a function.
• Function Types: Familiarize yourself with different types of functions, including linear, quadratic, and exponential functions. Understand their characteristics and how to graph them.

3. Polynomials and Factoring:

• Simplifying Polynomials: Practice combining like terms and using the distributive property.
• Factoring Polynomials: Master factoring techniques, including factoring out the greatest common factor (GCF), factoring trinomials, and factoring differences of squares.
• Solving Quadratic Equations: Learn to solve quadratic equations by factoring, using the quadratic formula, or completing the square.

4. Data Analysis:

• Interpreting Graphs and Charts: Practice reading and interpreting various types of graphs, including bar graphs, line graphs, scatter plots, and histograms.
• Data Representation: Understand how data can be represented in different ways (tables, graphs, etc.) and how to choose the most appropriate representation for a given dataset.
• Statistical Measures: Familiarize yourself with basic statistical measures such as mean, median, mode, and range.

5. Problem-Solving Strategies:

• Read Carefully: Pay close attention to the wording of each problem to understand what is being asked.
• Identify Key Information: Extract the important information from the problem statement.
• Choose the Right Strategy: Select the appropriate algebraic technique to solve the problem.
• Check Your Answer: Always check your answer to ensure it makes sense in the context of the problem.
