Convert the given system to an augmented matrix. 2x1 + 2x2 − x3 = 9 −x1 − x2 = −2 3x1 + 3x2 + x3 = 1 2 2 −1 9 −1 −1 0 −2 3 3 1 1 2 2 −1 9 −1 −1 −2 0 3 3 1 1 2 2 −1 9 −1 −1 0 2 3 3 1 1 2 −1 3 2 −1 3 −1 −2 1 9 0 1 2 −1 3 2 −1 3 −1 0 1 9 −2 1 correct: your answer is correct. find all solutions by reducing the system to echelon form and back substituting. (if there are an infinite number of solutions use s1 as your parameter. if there is no solution, enter no solution.) (x1, x2, x3) = incorrect: your answer is incorrect.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
