Answer

The solution is \( -3 \leq x < 4 \).

Solution

Solve the equation \( -4<4-2x\leq 10 \). Solve the system of inequalities by following steps: - step0: Solve for \(x\): \(\left\{ \begin{array}{l}-4<4-2x\\4-2x\leq 10\end{array}\right.\) - step1: Solve the inequality: \(\left\{ \begin{array}{l}x<4\\x\geq -3\end{array}\right.\) - step2: Find the intersection: \(-3\leq x<4\) The solution to the inequality \( -4<4-2x \leq 10 \) is \( -3 \leq x < 4 \). To graph this inequality, we need to plot the points on the number line where \( x = -3 \) and \( x = 4 \), and then shade the region between these points to represent the solution set. The graph of the inequality \( -4<4-2x \leq 10 \) is a closed interval from -3 to 4, including -3 but excluding 4.

Extra Insights

To solve the compound inequality \(-4 < 4 - 2x \leq 10\), we can split it into two parts and solve them separately. 1. For the first part, \(-4 < 4 - 2x\): \[ -4 < 4 - 2x \implies -4 - 4 < -2x \implies -8 < -2x \implies 4 > x \implies x < 4. \] 2. For the second part, \(4 - 2x \leq 10\): \[ 4 - 2x \leq 10 \implies -2x \leq 10 - 4 \implies -2x \leq 6 \implies x \geq -3. \] Putting the two parts together, we have: \[ -3 \leq x < 4. \] To graph this inequality on a number line, you would: - Draw an open circle at \(4\), indicating that \(4\) is not included. - Draw a closed circle at \(-3\), indicating that \(-3\) is included. - Shade the region between these points. This results in the range \([-3, 4)\) on the number line. Enjoy graphing!
