Chapter 2: Q.2.130 (page 192)

Solve the compound inequality. Graph the solution and write the solution in interval notation.
$2 - 5 x \leq - 3 o r 5 + 2 x \leq 3$

Short Answer

Expert verified

$S o l u t i o n : x \leq - 1 o r x \geq 1 I n t e r v a l N o t a t i o n : (- \infty, - 1] \cup [1, \infty)$

The graph of the solution is

Step by step solution

Step 1. Given information

$2 - 5 x \leq - 3 o r 5 + 2 x \leq 3$

Step 2.Solve Each inequalities

$2 - 5 x \leq - 3 o r 5 + 2 x \leq 3 2 - 5 x - 2 \leq - 3 - 2 5 + 2 x - 5 \leq 3 - 5 - 5 x \leq - 5 2 x \leq - 2 \frac{- 5 x}{- 5} \geq \frac{- 5}{- 5} \frac{2 x}{2} \leq \frac{- 2}{2} x \geq 1 x \leq - 1$

Step 3. Graph The Solution

Graph of $2 - 5 x \leq - 3$

Graph of $5 + 2 x \leq 3$

Merge the above graphs

Step 4.Solution and Interval Notation

$S o l u t i o n : x \leq - 1 o r x \geq 1 I n t e r v a l N o t a t i o n : (- \infty, - 1] \cup [1, \infty)$
