Answer the question in the picture (i will give brainliest to the right answer)

Which undefined geometric term is described as a location on a coordinate plane that is designed by an ordered pair (x, y) ?

Solve the triangle. a = 21°, c = 105°, c = 5

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
