∆DEF has vertices D(–4, 3), E(1, 2), and F(–3,–3). Determine the coordinates of the figure rotated 180° counterclockwise about the origin.

Aquadratic function f(x) has a turning point at (3,-7). what is the turning point of -f(x)?

For the following sequence determine the common difference (if it is an arithmetic sequence) or the common ratio (if it is a geometric sequence).

To complete your spring schedule, you must add calculus and physics. at 9: 30, there are three calculus sections and two physics sections; while at 11: 30, there are two calculus sections and three physics sections. how many ways can you complete your schedule if your only open periods are 9: 30 and 11: 30?
