B. -4 < b < 5
C. b < -3 or b > 0
D. All Real Numbers

Answer 1

thank yhu:)

Answer 2

2b+5<−1⟹2b<−6⟹b<−3
b-4>-4 ⟹ b>0

So Option C

Answer 3

What you have to do first is to isolate b: \(2b+5 < -1\)
It would be \(\large b< \frac{-1-5}{2}\) \(b<-3\)
Do the same with the second one
\(b > -4+4\)
\(b>0\)

\(b<-3\) or \(b>0\)
