The distance between points A and C can be found by solving for d in the equation e² + f² = d². Do you agree or disagree with this statement? Explain.

• disagree, Pythagorean Theorem used incorrectly

• disagree, Distance formula used incorrectly

• agree, Pythagorean Theorem used correctly

• agree, Distance formula used correctly

Explain how to find the distance between P(-1, 4) and Q(2, -3) and describe the relationship between the two points.

• Segment PQ is the hypotenuse of the right triangle found by finding the square root of the difference between the x coordinates and y coordinates.

• Segment PQ is the hypotenuse of the right triangle found by finding the difference between the x coordinates and y coordinates.

Erin is 3 years younger than twice Alex's age. Their ages combined are 33 years. How old are Alex and Erin. If x=Erin's age and y=Alex's age, choose the system that matches the situation.

• x + y = 33
  y = 2x - 3
• x + y = 33
  x = 2y - 3
• x + y = 33
  x = 3 - 2y
• x + y = 3
  x = 33 - 2y
