Math Problem Statement

answer

Find the correct midpoint and distance from the given options.

Solution

Let's analyze each of the given options to find the correct answer:

  1. Option 1:

    • Midpoint: 2
    • Distance from midpoint: 8
    • Equation: x+2=8|x + 2| = 8
    • Solving this equation gives x+2=8x + 2 = 8 or x+2=8x + 2 = -8.
    • This simplifies to x=6x = 6 or x=10x = -10.
    • However, the midpoint formula x1+x22=2\frac{x_1 + x_2}{2} = 2 should hold for x1=6x_1 = 6 and x2=10x_2 = -10, which satisfies the midpoint. This is incorrect because it represents the distance improperly.
  2. Option 2:

    • Midpoint: -8
    • Distance from midpoint: 2
    • Equation: x+8=2|x + 8| = 2
    • Solving gives x+8=2x + 8 = 2 or x+8=2x + 8 = -2.
    • This simplifies to x=6x = -6 or x=10x = -10.
    • The midpoint formula for x1=6x_1 = -6 and x2=10x_2 = -10 gives the correct midpoint of -8. This is the correct distance and midpoint.
  3. Option 3:

    • Midpoint: 8
    • Distance from midpoint: 8
    • Equation: x8=2|x - 8| = 2
    • Solving gives x8=2x - 8 = 2 or x8=2x - 8 = -2.
    • This simplifies to x=10x = 10 or x=6x = 6.
    • Midpoint calculation for x1=10x_1 = 10 and x2=6x_2 = 6 results in 8, but the distance is incorrect.
  4. Option 4:

    • Midpoint: 2
    • Distance from midpoint: 8
    • Equation: x2=8|x - 2| = 8
    • Solving gives x2=8x - 2 = 8 or x2=8x - 2 = -8.
    • This simplifies to x=10x = 10 or x=6x = -6.
    • Midpoint calculation for x1=10x_1 = 10 and x2=6x_2 = -6 results in 2, and the distance is 8.

Conclusion: The correct answer is Option 4, where the midpoint is 2, and the distance to either point is 8, satisfying the given equation x2=8|x - 2| = 8.
