Ответ:x<= пять вторых x>= -1

Answer 2

Problem Statement

The given inequality is: -1 <= 2x + 1 <= 6. We need to solve this inequality.

Solution

To solve the inequality, we will break it down into two separate inequalities and solve each one individually.

Inequality 1: -1 <= 2x + 1 To solve this inequality, we will subtract 1 from both sides: -1 - 1 <= 2x + 1 - 1 -2 <= 2x

Next, we will divide both sides by 2: -2/2 <= 2x/2 -1 <= x

So, the solution to the first inequality is x >= -1.

Inequality 2: 2x + 1 <= 6 To solve this inequality, we will subtract 1 from both sides: 2x + 1 - 1 <= 6 - 1 2x <= 5

Next, we will divide both sides by 2: 2x/2 <= 5/2 x <= 5/2

So, the solution to the second inequality is x <= 5/2.

Final Solution

Combining the solutions to both inequalities, we have: -1 <= x <= 5/2

Therefore, the solution to the given inequality is -1 <= x <= 5/2.
