Which statement best explains whether △pqr is congruent to △xyz? a. △pqr is congruent to △xyz because △pqr can be mapped to △xyz by a rotation of 180° about the origin. b.△pqr is congruent to △xyz because △pqr can be mapped to △xyz by a reflection across the y-axis followed by a reflection across the x-axis. c.△pqr is congruent to △xyz because △pqr can be mapped to △xyz by a translation 5 units down followed by a reflection across the y-axis. d.△pqr is not congruent to △xyz because there is no sequence of rigid motions that maps △pqr to △xyz.

(01.03 mc) which of the following is a step in simplifying the expression x multiplied by y to the power of 2 over x to the power of negative 3 multiplied by y to the power of 3, the whole to the power of negative 4. select one: a. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 7 multiplied by y to the power of negative 1. b. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of 12 multiplied by y to the power of negative 12. c. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of negative 3 multiplied by y to the power of 3. d. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 3 multiplied by y to the power of 3.
