Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

3x + 4y = 5 x- 3y = -7 solve by substitution

Lesson 9-3 for items 8-10, a square is drawn in the coordinate plane, with vertices as shown in the diagram. then the square is reflected across the x-axis. -2 4 8. the function that describes the reflection is (x, y) - a. (x, y-3). b. (x, y-6). c. (-x, y). d. (x,- y).
