Point D' is the image of D(-2, 1) under a reflection across the x-axis. What are the coordinates of D'?​

49xy +34y - 72z. determine the degree of the polynomial

12. decide whether each statement is always true, sometimes true, or never true. a. when corresponding points of an original figure and its reflection are connected, the resulting segments are all perpendicular to the line of reflection. b. when a point is reflected over a horizontal line, the y-coordinate of the point stays the same. answer both questions and explain

Polynomial that can be factored as (3x-4)(3x+4)
