Answer:

A.

[tex]$\left[-\frac{13}{2},\infty \right)$[/tex]

Step-by-step explanation:

Inequality given:

[tex]11\leq 6(n+4)-4n[/tex]

[tex]11\leq 6n+24-4n[/tex]

[tex]11\leq 2n+24[/tex]

[tex]11-24\leq 2n+24-24[/tex]

[tex]-13\leq 2n[/tex]

[tex]$\frac{-13}{2} \leq n$[/tex]

Interval Notation:

[tex]$\left[-\frac{13}{2},\infty \right)$[/tex]

We have:

[tex]$\{n \in \mathbb{R}:n\geq \frac{-13}{2} \}$[/tex]
