Class 11 Linear Inequalities

Class 11 Linear Inequalities- In mathematics, linear inequalities involve expressions with variables that are not necessarily equal. Class 11 linear inequalities typically cover the basics of solving and graphing linear inequalities. Here are some key concepts and methods you might study in this topic:

1. Linear Inequalities:

• A linear inequality is an inequality that involves a linear expression in one or more variables.
• The general form of a linear inequality in one variable x is ax+b>0 or ax+b<0, where a and b are real numbers.

2. Solving Linear Inequalities:

• Solving linear inequalities involves finding the values of the variable that satisfy the inequality.
• The solution to a linear inequality is usually expressed as an interval on the number line.

3. Graphical Representation:

• Linear inequalities can be represented graphically on a coordinate plane.
• The solution region is the shaded area that satisfies the inequality.

4. Interval Notation:

• Expressing solutions using interval notation is common in dealing with inequalities.
• For example, (a,b) represents the open interval between a and b.

5. Compound Inequalities:

• Compound inequalities involve more than one inequality, connected by “and” or “or.”
• For example, 2<x<5 is a compound inequality.

6. Systems of Linear Inequalities:

• A system of linear inequalities involves multiple linear inequalities with the same variables.
• The solution is the region that satisfies all the inequalities simultaneously.

7. Word Problems:

• Linear inequalities are often used to model and solve real-world problems, such as budgeting, production planning, and resource allocation.

8. Properties of Inequalities:

• Understanding how operations (addition, subtraction, multiplication, division) affect the direction of the inequality.

9. Testing Solutions:

• Substituting test points into the original inequality to check the validity of the solution.

10. Absolute Value Inequalities:

• Linear inequalities involving absolute values.

Example:

Consider the inequality 2x−3<5. To solve it:

• Add 3 to both sides: 2x<8
• Divide by 2: x<4

So, the solution is x∈(−∞,4).

In graphical terms, it would be a shaded region to the left of 4 on the number line.

Understanding these concepts will help you work with linear inequalities and apply them to various mathematical and real-world scenarios.
