-6x > -18 and 1 ≤ 2x + 5
-16 ≤ 6x + 2 < 14
Transcript text: Match each compound inequality on the left to the graph that represents its solution on the right.
\[
\begin{array}{l}
-5 x+9<-6 \text { or }-3 x+1 \geq 7 \\
-6 x>-18 \text { and } 1 \leq 2 x+5 \\
-16 \leq 6 x+2<14
\end{array}
\]
Solution
Solution Steps
Step 1: Identify the first compound inequality
The first compound inequality given is:
\[ -5x + 9 \leq -6 \quad \text{or} \quad -3x + 1 \geq 7 \]
Step 2: Solve the first part of the compound inequality
Solve \(-5x + 9 \leq -6\):
\[ -5x + 9 \leq -6 \]
Subtract 9 from both sides:
\[ -5x \leq -15 \]
Divide by -5 (remember to reverse the inequality sign):
\[ x \geq 3 \]
Step 3: Solve the second part of the compound inequality
Solve \(-3x + 1 \geq 7\):
\[ -3x + 1 \geq 7 \]
Subtract 1 from both sides:
\[ -3x \geq 6 \]
Divide by -3 (remember to reverse the inequality sign):
\[ x \leq -2 \]
Step 4: Combine the solutions
The solution to the compound inequality \(-5x + 9 \leq -6 \quad \text{or} \quad -3x + 1 \geq 7\) is:
\[ x \geq 3 \quad \text{or} \quad x \leq -2 \]
Step 5: Match the solution to the graph
Identify the graph that represents \(x \geq 3\) or \(x \leq -2\). The correct graph will have shading to the right of 3 and to the left of -2.
Final Answer
The graph that represents the solution \(x \geq 3\) or \(x \leq -2\) is the one with shading to the right of 3 and to the left of -2.
