Graph the inequality on a number line. \( \begin{array}{lll}\text { 25. } a>4 & \text { 26. } n \geq 8 & \text { 27. } 3 \geq x\end{array} \)

1. **\(a>4\)** - Draw a number line. - Mark the point \(a=4\) with an *open circle* since \(4\) is not included. - Shade the region to the right of \(4\) since \(a\) is greater than \(4\). 2. **\(n\geq8\)** - Draw a number line. - Mark the point \(n=8\) with a *closed circle* because \(8\) is included. - Shade the region to the right of \(8\) since \(n\) is greater than or equal to \(8\). 3. **\(3\geq x\)** - First, rewrite the inequality as \(x\leq3\) for clarity. - Draw a number line. - Mark the point \(x=3\) with a *closed circle* because \(3\) is included. - Shade the region to the left of \(3\) since \(x\) is less than or equal to \(3\).
