Short Answer

Expert verified

Solution of inequalities

$x \leq - 2 a n d x \geq - 4$

Graph of solution of inequalities

The solution in interval notation

$[- 4, - 2]$

Step by step solution

Step 1. Given information

Consider each inequality

$3 x + 7 \leq 1 a n d 2 x + 3 \geq - 5$

Step 2. Solve each inequality

$3 x + 7 \leq 1 3 x \leq 1 - 7 3 x \leq - 6 x \leq \frac{- 6}{3} x \leq - 2$ and $2 x + 3 \geq - 5 2 x \geq - 5 - 3 2 x \geq - 8 x \geq \frac{- 8}{2} x \geq - 4$

Step 3. Graph each inequality

For $x \leq - 2$

For $x \geq - 4$

Step 4. Graph number that make both inequality true. x≤-2 and x≥-4

The solution in interval notation

$[- 4, - 2]$
