Can someone me with this quick give me the right answer pleas me fast just say line 1=a or something like that so i know me 30 points

1. D

2. C

3. B

4. A

Step-by-step explanation:

1. x< -1  Open circle at -1   line goes to the left   D

2.  x≥ -1  Closed circle at -1 ( because of the equals sign)  line goes to the right   C

3.  x ≤ -1   Closed circle at -1 ( because of the equals sign)  line goes to the left   B

4.  x > -1  open circle at -1  lines goes to the right A

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

it would take 7/10 of an hour too fill the pool.
