Question

1. $4 \leq x$

Explanation:

Step1: Analyze the inequality on the number line

The inequality is \(2.4\leq x\). On a number line, for \(a\leq x\) (where \(a = 2.4\)), we use a closed - circle at the point \(x=a\) (because the equality part \(x = 2.4\) is included) and shade the line to the right (since \(x\) is greater than or equal to \(2.4\)).

Answer:

On the given number line, place a closed - circle at \(2.4\) and shade the line to the right of \(2.4\) (towards the positive infinity direction).
