Geometrically speaking, a parabola is defined as the set of points that are the same distance from a given point and a given line. The point is called the focus of the parabola and the line is called the directrix of the parabola. Suppose {P} is a parabola with focus (4,3) and directrix y=1. The point (8,6) is on {P} because (8,6) is 5 units away from both the focus and the directrix.

If we write the equation whose graph is {P} in the form $y=ax^2 + bx + c, then what is a+b+c?

Someone me i need with this stuff

:i need some real : a store sells shirts to the public at one pricing scale and wholesale at another pricing scale. the tables below describe the cost, y, of x shirts. (after tables) how do the slopes of the lines created by each table compare? the slope of the public table is 3/4 of the slope of the wholesale table.the slope of the wholesale table is 3/4 of the slope of the public table.the slope of the public table is 12 times greater than the slope of the wholesale table.the slope of the wholesale table is 12 times greater than the slope of the public table.

Factor this polynomial completely. 12x^2+ x-6
