Rvaries directly as s and inversely as t cubed. if r= 607.5 when s= 12 and r= 2, find r when s=42 and c= 6

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

Module 10 coordinate proof using slope and distance answers is quadrilateral abcd a parallelogram? explain how you know.

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]
