2. Understand the meaning of the solution set of linear inequalities of one variable.

3. Be able to determine the solution set of a group of inequalities with the help of the number line.

Group of linear inequalities of one variable

Several linear inequalities containing the same unknowns are combined to form a group of linear inequalities of one variable.

Solution set of linear inequalities of one variable

The common part of the solution set of several linear inequalities of one variable is called the solution set of the group of linear inequalities of one variable

The solution set rules of inequality groups

Take the greater

Take the smaller one

Find between small, big and big

I can’t understand big or small

1. Select the value range of a appropriately so that 1.7＜x＜a is an integer solution:

(1)x has only one integer solution;

(2)x does not have an integer solution.

2. The solution set of the inequality group x+9＜5x+1 x＞m+1 is x＞2, then the value range of m is ().

(A)m≤2 (B)m≥2 (C)m≤1 (D)m≥1
