To address the first part of your question regarding the inequality \( 35 < 7x \):
-
Open or Closed Circle: You would use an open circle because the inequality does not include equality (it’s a "less than" rather than "less than or equal to").
-
Arrow Direction: The arrow on the number line would point to the right. This is because you're solving for \( x \) in the inequality; when you manipulate the inequality (by dividing both sides by \( 7 \)), you get \( x > 5 \).
For Question 10, let's analyze the inequalities you've provided to match them with their graphed solutions:
-
\(-5(x + 5) > -15\):
- Solving:
- Distribute: \(-5x - 25 > -15\)
- Add 25: \(-5x > 10\)
- Divide by -5 (remember to flip the inequality sign): \(x < -2\)
- Solving:
-
\(-3(x - 12) > 0\):
- Solving:
- Distribute: \(-3x + 36 > 0\)
- Subtract 36: \(-3x > -36\)
- Divide by -3 (flip the inequality): \(x < 12\)
- Solving:
-
\((1/4)(8x + 16) > -4\):
- Solving:
- Multiply by 4: \(8x + 16 > -16\)
- Subtract 16: \(8x > -32\)
- Divide by 8: \(x > -4\)
- Solving:
-
\(8x < 4x + 28\):
- Solving:
- Subtract \(4x\): \(4x < 28\)
- Divide by 4: \(x < 7\)
- Solving:
Now we can match the inequalities with their graphs based on the gathered information:
- \(-5(x + 5) > -15\): Corresponds to \(x < -2\)
- \(-3(x - 12) > 0\): Corresponds to \(x < 12\)
- \((1/4)(8x + 16) > -4\): Corresponds to \(x > -4\)
- \(8x < 4x + 28\): Corresponds to \(x < 7\)
You can match these inequalities with their respective graphs based on the information above!
