Math Problem Statement

The solution to which inequality is graphed below?

Solution

To determine which inequality corresponds to the given graph, let's analyze the information:

Step 1: Graph Analysis

  • The graph shows a shaded portion between 4-4 and 44, including both endpoints.
  • This suggests the solution is bounded between 4-4 and 44, inclusive.
  • Mathematically, this can be expressed as: 4s4-4 \leq s \leq 4

Step 2: Check each option

We will solve each inequality to see if it fits the solution range [4,4][-4, 4].

  1. 3s+7>53s + 7 > -5: 3s+7>5    3s>12    s>43s + 7 > -5 \implies 3s > -12 \implies s > -4 This does not include s=4s = -4 and has no upper bound, so it's not the solution.

  2. 4s+10264s + 10 \geq -26: 4s+1026    4s36    s94s + 10 \geq -26 \implies 4s \geq -36 \implies s \geq -9 This does not have an upper bound and starts at 9-9, so it doesn't match.

  3. 3s48-3s - 4 \geq 8: 3s48    3s12    s4-3s - 4 \geq 8 \implies -3s \geq 12 \implies s \leq -4 This covers values less than or equal to 4-4 and has no upper bound on the positive side. Therefore, it doesn't match.

  4. 3s75-3s - 7 \leq 5: 3s75    3s12    s4-3s - 7 \leq 5 \implies -3s \leq 12 \implies s \geq -4 Solving for the other side: 3s75    s4-3s - 7 \leq 5 \implies s \leq 4 Thus, this simplifies to: 4s4-4 \leq s \leq 4 This matches the graph.

Conclusion

The correct inequality is: 3s75\boxed{-3s - 7 \leq 5}
