Answer 1

Answer:

answer is the first one

Answer 2

Answer:

A.

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

Step-by-step explanation:

Inequality given:

$11\leq 6(n+4)-4n$

$11\leq 6n+24-4n$

$11\leq 2n+24$

$11-24\leq 2n+24-24$

$-13\leq 2n$

$\frac{-13}{2} \leq n$

Interval Notation:

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

We have:

$\{n \in \mathbb{R}:n\geq \frac{-13}{2} \}$
