Which conjunction or disjunction equivalent to the open sentence 4 –3|n + 2| ≥ 1?
Start by solving for |n+2| At that point, follow these rules: \[If\ |x| < y,\ then\ -y<x<y \\ If\ |x| > y,\ then\ x<-y\ OR\ x>y\] Once you have the inequality without absolute values, solve for n.
Can you give me the sentences?
? Not sure what that part of the question is asking. All I know is that a conjunction is a compound inequality (a<x<b) and a disjunction is a split up inequality (x<a OR x>b)
A. n + 2 ≥ 1 and n + 2 ≤ –1 B. n + 2 ≤ 1 and n + 2 ≥ –1 C. n + 2 ≤ 1 and n − 2 ≥ −1 D. n + 2 ≥ 1 or n – 2 ≤ 1

First, isolate the absolute value: |dw:1389409890595:dw|
