Line segment ab with endponts a(4,16) and b(20,4) lies in the coordinate plane. the segment will be dialated with a scale factor of 3/4 and a center at the orgin to create line segment a'b'. what will be the length of line segment a'b'

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

Hardest math question of all time can you solve the equation. check for extraneous solutions.9∣9-8x∣ = 2x+3

Math it's appreciated. (picture provided)
