Which number line best represents the solution to the inequality -4x + 29 > 19?
A.
B.
C.
D.

To solve the inequality \(-4x + 29 > 19\), let's proceed step by step.

### Step 1: Simplify the inequality

Subtract 29 from both sides:

\[
-4x + 29 - 29 > 19 - 29
\]

\[
-4x > -10
\]

### Step 2: Solve for \(x\)

To isolate \(x\), divide both sides by \(-4\). **Remember**, dividing by a negative number reverses the inequality sign:

\[
x < \frac{-10}{-4}
\]

\[
x < 2.5
\]

### Solution:

The inequality is \(x < 2.5\). This represents all values less than 2.5.

On the number line, this would be shown as an open circle at 2.5 (because \(x\) is *less than* 2.5, not equal to it), with the shading extending to the left to represent values smaller than 2.5.

### Now, which number line best represents this?

Look for the option that shows:
- An open circle at 2.5
- A shaded line extending to the left of 2.5

**Relative Questions:**
1. What happens if we divide an inequality by a negative number?
2. How do we represent inequalities on a number line?
3. What would the solution be for the inequality \(-4x + 29 \leq 19\)?
4. Can you solve a similar inequality, like \(-3x + 10 > 7\)?
5. What if the inequality were \(4x + 29 > 19\), how would that change the solution?

**Tip**: Always remember to reverse the inequality sign when multiplying or dividing by a negative number!
