Linear Equations in One Variable, Algebra 2 1.2 worksheet answers

Linear equations in one variable are equations that can be written in the form ax + b = c, where a, b, and c are constants and x is the variable. To solve a linear equation, we need to find the value of x that makes the equation true.

Example:Solve for x in the equation 2x + 5 = 13.
Solution:Subtract 5 from both sides of the equation: 2x = 8. Divide both sides by 2: x = 4.

Linear Inequalities in One Variable

Linear inequalities in one variable are inequalities that can be written in the form ax + b < c or ax + b > c, where a, b, and c are constants and x is the variable. To solve a linear inequality, we need to find the values of x that make the inequality true.

So, whether you’re struggling with quadratic equations or polynomial functions, you’ll find the help you need right here.

Example:Solve the inequality 3x – 2 < 10.
Solution:Add 2 to both sides of the inequality: 3x < 12. Divide both sides by 3: x < 4.

Systems of Linear Equations

Systems of linear equations are sets of two or more linear equations that are solved simultaneously. To solve a system of linear equations, we need to find the values of the variables that make all the equations true.

Example:Solve the system of equations:
- x + y = 5
- 2x – y = 1
Solution:Use the substitution method to solve the system. Solve the first equation for x: x = 5
y. Substitute this expression for x into the second equation

2(5
- y)
- y =

Applications of Linear Equations and Inequalities

Linear equations and inequalities can be used to model and solve a variety of real-world problems. Some common applications include:

Distance, rate, and time problems:These problems involve finding the distance traveled, the rate of travel, or the time taken to travel a certain distance.
Mixture problems:These problems involve finding the amount of each ingredient needed to create a mixture with a desired concentration or volume.
Profit and loss problems:These problems involve finding the profit or loss made when buying and selling items at different prices.

Illustrative Examples: Algebra 2 1.2 Worksheet Answers

This section provides illustrative examples to reinforce the concepts covered in Algebra 2 1.2.

Each example is designed to clearly demonstrate the application of these concepts in solving real-world problems.

Simplifying Radical Expressions

Problem:Simplify the expression √(27x^3y^2).
Solution:√(27x^3y^2) = √(9x^2y^2 – 3x) = 3x|y|√3x

Rationalizing Denominators

Problem:Rationalize the denominator of the expression 1/(√5 – 2).
Solution:Multiply and divide by the conjugate of the denominator: 1/(√5 – 2) = 1/(√5 – 2) – (√5 + 2)/(√5 + 2) = (√5 + 2)/3

Solving Radical Equations

Problem:Solve the equation √(x + 5) = 3.
Solution:Square both sides of the equation: (√(x + 5))^2 = 3^2, which simplifies to x + 5 = 9. Subtracting 5 from both sides, we get x = 4.
