#### A. 9 > 3 - 4x
Solve:
- Subtract 3 from both sides:
$ 9 - 3 > -4x $ → $ 6 > -4x $
- Divide by -4 (remember: flip inequality when dividing by negative):
$ \frac{6}{-4} < x $ → $ -\frac{3}{2} < x $ or $ x > -1.5 $
✔ Solution: $ x > -1.5 $ → open circle at -1.5, arrow to the right.
---
#### B. 12 – 13 ≤ 8(–4 + 3x)
Simplify left side:
$ -1 ≤ 8(-4 + 3x) $ → $ -1 ≤ -32 + 24x $
Add 32:
$ 31 ≤ 24x $
Divide by 24:
$ x ≥ \frac{31}{24} $ ≈ $ x ≥ 1.29 $
✔ Solution: $ x ≥ 1.29 $ → closed circle at ~1.3, arrow to the right.
---
#### C. –20 > 5(1 – 7x)
Distribute:
$ -20 > 5 - 35x $
Subtract 5:
$ -25 > -35x $
Divide by -35 (flip inequality):
$ \frac{-25}{-35} < x $ → $ \frac{5}{7} < x $ → $ x > \frac{5}{7} $ ≈ $ x > 0.714 $
✔ Solution: $ x > 0.714 $ → open circle at ~0.7, arrow to the right.
---
#### D. –3x – 7 ≥ 2 – 4x
Move variables to one side:
Add 4x to both sides:
$ x - 7 ≥ 2 $
Add 7:
$ x ≥ 9 $
✔ Solution: $ x ≥ 9 $ → closed circle at 9, arrow to the right.
---
#### E. –8x – 3 ≤ –83
Add 3:
$ -8x ≤ -80 $
Divide by -8 (flip inequality):
$ x ≥ 10 $
✔ Solution: $ x ≥ 10 $ → closed circle at 10, arrow to the right.
---
#### F. 9 + 5x < 59
Subtract 9:
$ 5x < 50 $
Divide by 5:
$ x < 10 $
✔ Solution: $ x < 10 $ → open circle at 10, arrow to the left.
---
#### G. 13 + 9x ≤ 1 + 10x
Subtract 9x:
$ 13 ≤ 1 + x $
Subtract 1:
$ 12 ≤ x $ → $ x ≥ 12 $
✔ Solution: $ x ≥ 12 $ → closed circle at 12, arrow to the right.
---
#### H. –5 + 3x ≥ 13
Add 5:
$ 3x ≥ 18 $
Divide by 3:
$ x ≥ 6 $
✔ Solution: $ x ≥ 6 $ → closed circle at 6, arrow to the right.
---
#### I. 4x + 7 ≤ –5 – 2x
Add 2x:
$ 6x + 7 ≤ -5 $
Subtract 7:
$ 6x ≤ -12 $
Divide by 6:
$ x ≤ -2 $
✔ Solution: $ x ≤ -2 $ → closed circle at -2, arrow to the left.
---
#### J. 3x – 4 > 2x – 3x
Simplify right side: $ 2x - 3x = -x $
So: $ 3x - 4 > -x $
Add x: $ 4x - 4 > 0 $
Add 4: $ 4x > 4 $
Divide by 4: $ x > 1 $
✔ Solution: $ x > 1 $ → open circle at 1, arrow to the right.
---
#### K. –4 + 4 ≤ 5x + 12
Simplify left: $ -8 ≤ 5x + 12 $
Subtract 12: $ -20 ≤ 5x $
Divide by 5: $ -4 ≤ x $ → $ x ≥ -4 $
✔ Solution: $ x ≥ -4 $ → closed circle at -4, arrow to the right.
---
#### L. –10(–13 + x) ≥ –40
Distribute: $ 130 - 10x ≥ -40 $
Subtract 130: $ -10x ≥ -170 $
Divide by -10 (flip inequality): $ x ≤ 17 $
✔ Solution: $ x ≤ 17 $ → closed circle at 17, arrow to the left.
