Question

graph the solution to the inequality on the number line.
|4x + 12| < 16

Explanation:

Step1: Solve the inequality

$$\begin{align*} -16&<4x + 12<16\\ -16-12&<4x<16 - 12\\ -28&<4x<4\\ \frac{-28}{4}&

Step2: Graph the solution

On the number line, draw an open circle at \(x = - 7\) and \(x = 1\) (because the inequality is strict, i.e., \( <\) not \( \leq\)). Then shade the region between \(x=-7\) and \(x = 1\).

Answer:

The solution of the inequality \(|4x + 12|<16\) is \(-7
