Explanation:

Response
Question 3: Solve \( 9x + 7 \leq -20 \)

Step 1: Subtract 7 from both sides

To isolate the term with \( x \), we subtract 7 from both sides of the inequality.
\( 9x + 7 - 7 \leq -20 - 7 \)
\( 9x \leq -27 \)

Step 2: Divide both sides by 9

To solve for \( x \), we divide both sides of the inequality by 9. Since 9 is positive, the direction of the inequality sign remains the same.
\( \frac{9x}{9} \leq \frac{-27}{9} \)
\( x \leq -3 \) Wait, but the option A is \( x \leq -3 \)? Wait, the original options: A. \( x \leq -3 \), B. \( x \geq -3 \), C. \( x \leq \frac{7}{9} \), D. \( x \geq 18 \). So the correct answer should be A.

Step 1: Subtract 4 from both sides

To isolate the term with \( x \), we subtract 4 from both sides of the inequality.
\( 8x + 4 - 4 \geq -4 - 4 \)
\( 8x \geq -8 \)

Step 2: Divide both sides by 8

To solve for \( x \), we divide both sides of the inequality by 8. Since 8 is positive, the direction of the inequality sign remains the same.
\( \frac{8x}{8} \geq \frac{-8}{8} \)
\( x \geq -1 \)
Which matches option A.

Step 1: Check Option A

Substitute \( x=-17 \) into \( 2x - 9 \): \( 2\times(-17)-9=-34 - 9=-43
eq25 \)

Step 2: Check Option B

Substitute \( x = -17 \) into \( 15 - x \): \( 15-(-17)=15 + 17 = 32
eq - 2 \)

Step 3: Check Option C

Substitute \( x=-17 \) into \( 13 - 2x \): \( 13-2\times(-17)=13 + 34 = 47
eq - 25 \)

Step 4: Check Option D

Substitute \( x=-17 \) into \( 3x + 19 \): \( 3\times(-17)+19=-51 + 19=-32 \)

Answer:

A. \( x \leq -3 \)

Question 4: Solve \( 8x + 4 \geq -4 \)
