After solving ( 7-2x\le 1 ) and showing it on the number line, which option is correct?

Answer and explanation

Correct answer: ( x\ge 3 ), closed at ( 3 ), shaded right

The direct answer is option C: x≥3, with a closed point at 3 and shading to the right. Solve 7-2x≤1. Subtract 7: -2x≤-6. Divide by -2, and reverse the sign because the divisor is negative: x≥3. Equality is allowed in the original inequality, so x=3 belongs to the solution set; therefore the point is closed. Numbers greater than 3 also work, so shade right. Option A incorrectly shades left and uses the wrong direction. Option B excludes 3 even though equality is allowed. Option D has the correct rightward direction but incorrectly uses a strict sign and an open point. Always check a value: x=4 gives 7-8=-1≤1, confirming the right side.
