HELP! I'll give brainliest.

gavmur [86]

Answer:

-4 < x ≤ -3

Step-by-step explanation:

The compound inequality needs to be separated into its two parts in order to obtain a solution.

We can do a little preliminary work to make the solutions easier.

2x +6 ≤ x +3 < 3x +11 . . . . . given

x +3 ≤ 0 < 2x +8 . . . . . . . . subtract x+3

x +3 ≤ 0

x ≤ -3 . . . . . . . subtract 3

<h3>right side</h3>

0 < 2x +8

0 < x +4 . . . . divide by 2

-4 < x . . . . . . subtract 4

<h3>solution</h3>

Now, we can rearrange these back into a compound inequality.

-4 < x ≤ -3

_____

The graphing calculator shows the same solution.
