Question

Solve the conjunction and describe the solution set.

–5 ≤ 3m + 1 < 4

A.
m ≥ –2 and m < 1

B.
m ≤ –2 or m > 1

C.
m ≥ and m <

D.
m ≥ or m <

Answer 1

All you need to do is solve for m in the middle.
First you need to subtract 1 from all: \[-6\le3m <3\]
Then you need to divide by 3 from all: \[-2lem <1\]
Thus you should get A for your answer

Answer 2

[-2,1)
