Since both
ExplainAnswer and
TeachTopic are false, we will only provide the
Final Answer after solving all 8 inequalities step by step.
---
We’ll solve each inequality one at a time, then describe how to graph the solution (even though we can’t draw here, we’ll note key points like open/closed circle and direction).
---
Problem 1: -a - 2 > 8
Step 1: Add 2 to both sides
→ -a > 10
Step 2: Multiply both sides by -1 → remember to flip the inequality sign!
→ a < -10
Graph: Open circle at -10, arrow pointing left.
---
Problem 2: -11p - 4 > -15
Step 1: Add 4 to both sides
→ -11p > -11
Step 2: Divide by -11 → flip the inequality
→ p < 1
Graph: Open circle at 1, arrow pointing left.
---
Problem 3: 27 ≤ 7x + 6
Step 1: Subtract 6 from both sides
→ 21 ≤ 7x
Step 2: Divide by 7
→ 3 ≤ x or x ≥ 3
Graph: Closed circle at 3, arrow pointing right.
---
Problem 4: 8k + 6 ≤ 94
Step 1: Subtract 6
→ 8k ≤ 88
Step 2: Divide by 8
→ k ≤ 11
Graph: Closed circle at 11, arrow pointing left.
---
Problem 5: 1 + 4x ≤ 31
Step 1: Subtract 1
→ 4x ≤ 30
Step 2: Divide by 4
→ x ≤ 7.5
Graph: Closed circle at 7.5, arrow pointing left.
*(Note: On number line, 7.5 is halfway between 7 and 8)*
---
Problem 6: 3r + 3 ≥ -12
Step 1: Subtract 3
→ 3r ≥ -15
Step 2: Divide by 3
→ r ≥ -5
Graph: Closed circle at -5, arrow pointing right.
---
Problem 7: -4 < (x - 2)/2
Step 1: Multiply both sides by 2
→ -8 < x - 2
Step 2: Add 2 to both sides
→ -6 < x or x > -6
Graph: Open circle at -6, arrow pointing right.
---
Problem 8: (-9 + a)/15 > 1
Step 1: Multiply both sides by 15
→ -9 + a > 15
Step 2: Add 9 to both sides
→ a > 24
Graph: Open circle at 24, arrow pointing right.

① a < -10
② p < 1
③ x ≥ 3
④ k ≤ 11
⑤ x ≤ 7.5
⑥ r ≥ -5
⑦ x > -6
⑧ a > 24
