Solving Equations and Inequalities

Solving equations and inequalities is a fundamental skill in algebra. In Chapter 6, students will learn how to solve one-step and two-step equations, as well as understand the concept of inequality and how to solve inequalities.

Solving One-Step and Two-Step Equations

• To solve a one-step equation, isolate the variable on one side of the equation.
• To solve a two-step equation, first isolate the variable term on one side of the equation, then isolate the variable.

Solving Inequalities

• An inequality is a statement that two expressions are not equal.
• To solve an inequality, isolate the variable on one side of the inequality sign.

Proportional Relationships: Big Ideas Math Chapter 6 Answer Key

Proportional relationships are relationships between two variables where the ratio of the variables is constant. In Chapter 6, students will learn how to define proportional relationships, write and solve proportions, and identify proportional relationships in real-world contexts.

Defining Proportional Relationships

• A proportional relationship is a relationship between two variables where the ratio of the variables is constant.
• The constant ratio is called the constant of proportionality.

Writing and Solving Proportions

• A proportion is an equation that states that two ratios are equal.
• To solve a proportion, cross-multiply and solve for the unknown variable.

Functions

Functions are a fundamental concept in algebra and mathematics. In Chapter 6, students will learn how to define functions, represent them using tables, graphs, and equations, and identify different types of functions.

Defining Functions

• A function is a relation that assigns to each element of a set a unique element of another set.
• The set of elements for which the function is defined is called the domain.
• The set of elements that the function assigns is called the range.

Representing Functions, Big ideas math chapter 6 answer key

• Functions can be represented using tables, graphs, and equations.
• A table shows the input and output values of the function.
• A graph shows the relationship between the input and output values of the function.
• An equation expresses the function as an algebraic expression.

Systems of Equations

Systems of equations are sets of two or more equations that are solved simultaneously. In Chapter 6, students will learn how to solve systems of equations using various methods, including substitution and elimination.

Solving Systems of Equations

• The substitution method involves substituting the value of one variable from one equation into the other equation.
• The elimination method involves adding or subtracting the equations to eliminate one of the variables.

Applications of Functions

Functions have numerous applications in real-world situations. In Chapter 6, students will learn how to use functions to model real-world problems, including problems in science, economics, and everyday life.

Modeling Real-World Situations

• Functions can be used to model a variety of real-world situations, such as the motion of an object, the growth of a population, or the cost of a product.
• By modeling a situation with a function, we can make predictions and solve problems.

FAQ Overview

What is the significance of solving equations and inequalities?

Solving equations and inequalities is crucial for understanding the relationships between variables and finding unknown values. It forms the basis for more advanced mathematical concepts and applications in various fields.

How can I identify proportional relationships in real-world contexts?

Proportional relationships are often characterized by constant ratios between variables. Look for situations where one variable increases or decreases at a consistent rate relative to another variable.

What are the key properties of functions?

Functions have specific properties, such as domain, range, and inverse. Understanding these properties helps in analyzing and representing functions in different forms.
