Study Online and Download Notes of Mathematics 9th Unit 7: Linear Equations and Inequalities. In this unit we will extend the study of previously learned skills to the solution of equations with rational coefficients of Unit 2 and the equations involving radicals and absolute value.
Study Online and Download Notes of Mathematics 9th Unit 7: Linear Equations and Inequalities. In this unit we will extend the study of previously learned skills to the solution of equations with rational coefficients of Unit 2 and the equations involving radicals and absolute value. Finally, after defining inequalities, and recalling their trichotomy, transitive, additive and multiplicative properties we will use them to solve linear inequalities with rational coefficients.
After studying this unit, the students will be able to:
- Recall linear equation in one variable.
- Solve linear equation with rational coefficients.
- Reduce equations, involving radicals, to simple linear form and find their solutions.
- Define absolute value.
- Solve the equation, involving absolute value, in one variable.
- Define inequalities ( >, <) and ( > , <)
- Recognize properties of inequalities (i.e., trichotomy, transitive, additive and multiplicative).
- Solve linear inequalities with rational coefficients.
