Question

Help me please djdjdd

Answer 1

Answer:

-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.

Answer 2

Answer:

$-1$

Step-by-step explanation:

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

9>-5x+4

and

$-5x+4\geq -11$

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:

$-5x+4\geq -11$

Subtract 4 from both sides:a

$-5x\geq -15$

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

$x\leq 3$

Now add the equations back together:

$-1$
