Chapter 2: Q. 401 (page 195)

Solve each inequality, graph the solution, and write the solution in interval notation.
$- 6 \leq 4 x - 2 < - 2$

Short Answer

Expert verified

Solution of inequality:

$- 2 \leq x < 0$

Graph the numbers that make both inequalities true:

The solution in interval notation:

$[- 2, 0)$

Step by step solution

Step 1. Given information

Consider the inequality

$- 6 \leq 4 x - 2 < - 2$

Step 2. Solve the inequality −6 ≤ 4x − 2 < −2

Add 2 to all parts:

$- 6 + 2 \leq 4 x - 2 + 2 < - 2 + 2$

Simplify:

$- 4 \leq 4 x < 0$

Divide each part by 4:

$\frac{- 8}{4} \leq \frac{4 x}{4} < \frac{0}{4}$

Simplify:

$- 2 \leq x < 0$

Step 3. Graph the solution of inequality −2 ≤ x < 0

The solution in interval notation:

$[- 2, 0)$
