which one is the answer

Solution

Let's analyze the options to find the correct equation for the given situation.

The general form of an absolute value equation for distance:

If the midpoint is mm and the distance from the midpoint to either point is dd, the equation can be written as: xm=d|x - m| = d This represents the distance from xx to the midpoint mm, which equals dd.

Analyzing the Options:

  • Top Left:

    • Midpoint = 6, Distance = 3.
    • Equation given: x+6=3|x + 6| = 3.
    • This equation is incorrect because it should be x6=3|x - 6| = 3, not x+6=3|x + 6| = 3, based on the general form.
  • Top Right:

    • Midpoint = 3, Distance = 6.
    • Equation given: x3=6|x - 3| = 6.
    • This equation is correct because it follows the correct form xm=d|x - m| = d, where m=3m = 3 and d=6d = 6.
  • Bottom Left (Selected):

    • Midpoint = 6, Distance = 3.
    • Equation given: x6=3|x - 6| = 3.
    • This equation is correct because it matches the form xm=d|x - m| = d with m=6m = 6 and d=3d = 3.
  • Bottom Right:

    • Midpoint = 3, Distance = 6.
    • Equation given: x+3=6|x + 3| = 6.
    • This equation is incorrect because it should be x3=6|x - 3| = 6, not x+3=6|x + 3| = 6.

Conclusion:

The correct answer is the Bottom Left option, where the equation is x6=3|x - 6| = 3.
