The correct answer is: D.

The solution to the compound inequality 0 ≤ -2x + 6 < 16, we can solve each part separately:

Solve 0 ≤ -2x + 6:

Start with the inequality 0 ≤ -2x + 6

Add 2x to both sides: 2x ≤ 6

Divide by 2 (since the coefficient of x is -2) and reverse the inequality sign: x ≥ 3

Solve -2x + 6 < 16:

Start with the inequality -2x + 6 < 16

Subtract 6 from both sides: -2x < 10

Divide by -2 (and reverse the inequality sign): x > -5

Combine the two inequalities: x ≥ 3 and x > -5

The solution to the compound inequality is x > 3

Now, let's analyze the options:

A) (-5, 3] - This represents numbers between -5 and 3, including -5 but excluding 3. This is not the correct answer.

B) -[5, 3) - This represents numbers between -5 and 3, excluding both -5 and 3. This is not the correct answer.

C) [-5, 3) - This represents numbers between -5 and 3, including -5 but excluding 3. This is not the correct answer.

D) (-5, 3) - This represents numbers between -5 and 3, excluding both -5 and 3. This is the correct answer.

Therefore, the correct answer is D) number line has -14 to 10 is (-5, 3).
