-1 < x ≤ 3

Step-by-step explanation:

First, we need to simplify this inequality.

9 > -5x + 4 ≥ -11 (Given)

5 > -5x ≥ -15 (Subtract 4 on both sides)

-1 < x ≤ 3 (Divide -5 on both sides)

Note that the signs flip due to dividing by a negative number.

Step-by-step explanation:

Let's take two equations from this and them put them back together! So:

9>-5x+4

and

For the first one:

9>-5x+4

Subtract 4 from both sides

5>-5x

Then divide by -5 (Remember to change the direction of the sign!):

-1<x

Now onto the second one:

Subtract 4 from both sides:a

Then divide by -5 (Remember to change the direction of the sign!):

Now add the equations back together:

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
