Answer:


\boxed{\sf{r < -4\quad r\geq 2}}

Explanation:

Isolate the term of r.

1. r+5<1

First, subtract by 5 from both sides.

r+5-5<1-5

Solve.

r<-4

2. r-1≥1

Add by 1 from both sides.

r-1+1≥1+1

Solve.

Add the numbers from left to right.

r≥2

Therefore, the correct answer is r<-4 and r≥2.

I hope this helps, let me know if you have any questions.
