Quick Solutions to Common Problems
Example Problems and Solutions
To give you a better understanding, here’s a breakdown of a few common problems you might find in the Algebra 1 8.2 worksheet, along with their quick solutions.
Problem 1: Solving a Linear Equation
Equation: 2x + 5 = 15
Solution:
- Subtract 5 from both sides: [ 2x = 10 ]
- Divide by 2: [ x = 5 ]
Problem 2: Using Properties of Equality
Equation: 3(x - 2) = 12
Solution:
- Distribute the 3: [ 3x - 6 = 12 ]
- Add 6 to both sides: [ 3x = 18 ]
- Divide by 3: [ x = 6 ]
Problem 3: Graphing a Linear Equation
Equation: y = 2x + 1
Solution:
- Identify the slope (2) and y-intercept (1).
- Plot the y-intercept (0,1).
- Use the slope to find another point. From (0,1), go up 2 and right 1 to (1,3).
- Draw the line through the points.
Table of Common Algebraic Formulas
To aid your understanding, here's a helpful table of common algebraic formulas that you can refer to while working through your problems:
<table> <tr> <th>Formula</th> <th>Description</th> </tr> <tr> <td>y = mx + b</td> <td>Slope-intercept form of a line</td> </tr> <tr> <td>ax^2 + bx + c = 0</td> <td>Standard form of a quadratic equation</td> </tr> <tr> <td>m = (y2 - y1) / (x2 - x1)</td> <td>Slope of a line</td> </tr> <tr> <td>y - y1 = m(x - x1)</td> <td>Point-slope form of a line</td> </tr> </table>
Tips for Success in Algebra 1
