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

<h3>left side</h3>

  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.
