Which diagram represents the type of solution to this system of equations? 7x − 12y + z = -1 8x − 10y = 5 21x − 36y + 3z = -3

We have enough material to build a fence around a station that has a perimeter of 180 feet the width of the rectangular space must be 3 1/4 feet what must the length be

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
