Examples and Explanations

In this section, we will provide detailed explanations and solutions to a few representative problems from Problem Set 5.1. These examples will illustrate the concepts and techniques discussed in the lesson.

Problem 1: Calculating the Area of a Triangle

Problem: Calculate the area of a triangle with a base of 10 cm and a height of 8 cm.

Solution:

• The formula for the area of a triangle is: Area = (1/2)- base – height
• Substitute the given values into the formula: Area = (1/2)- 10 cm – 8 cm
• Calculate the area: Area = 40 cm²

Therefore, the area of the triangle is 40 cm ².

Problem 2: Finding the Volume of a Cylinder

Problem: Find the volume of a cylinder with a radius of 5 cm and a height of 10 cm.

Solution:

• The formula for the volume of a cylinder is: Volume = π- radius ²– height
• Substitute the given values into the formula: Volume = π- 5 cm ²– 10 cm
• Calculate the volume: Volume ≈ 785.4 cm³

Therefore, the volume of the cylinder is approximately 785.4 cm ³.

Problem 3: Solving a Linear Equation

Problem: Solve the equation: 2x + 5 = 15

Solution:

• Subtract 5 from both sides: 2x = 10
• Divide both sides by 2: x = 5

Therefore, the solution to the equation is x = 5.

Methods and Procedures

Problem Set 5.1 introduces various methods and procedures for solving linear equations and inequalities.

These methods include:

• Substitution
• Elimination
• Graphing

Substitution

Substitution involves replacing a variable in an equation with an expression that is equivalent to that variable. This method is useful when one variable is expressed in terms of the other.

For example, to solve the system of equations:

x + y = 5 x

y = 1

We can substitute the second equation into the first equation to eliminate y:

x + (x

y) = 5

2x

y = 5

Solving for x gives us x = 3. Substituting this value back into either original equation gives us y = 2.

Elimination

Elimination involves adding or subtracting equations to eliminate one of the variables. This method is useful when both variables are expressed in terms of each other.

For example, to solve the system of equations:

2x + 3y = 11 x

y = 1

We can add the two equations to eliminate y:

3x + 2y = 12

Solving for x gives us x = 4. Substituting this value back into either original equation gives us y = 3.

Graphing

Graphing involves plotting the solutions of an equation or inequality on a coordinate plane. This method is useful for visualizing the relationship between the variables.

For example, to solve the inequality:

y > 2x

1

We can graph the line y = 2x – 1 and shade the region above the line. The solutions to the inequality are all the points that lie in the shaded region.

Comparison of Methods

The choice of which method to use to solve a system of equations or inequalities depends on the specific equations or inequalities involved.

• Substitution is typically the simplest method to use when one variable is expressed in terms of the other.
• Elimination is typically the best method to use when both variables are expressed in terms of each other.
• Graphing is typically the best method to use when visualizing the relationship between the variables is important.
