Substitute the values of x and y into the expression -3x2 + 2y2 + 5xy - 2y + 5x2 - 3y2. Match that value to one of the numbers. 1. x = 0.5, y = 1.665 2. x = -1, y = -3 -1 3. x = , y = 14 4. x = 0, y = 2.5 9.17 5. x = √2, y = √2 0.44 6. x = 2, y = -1 -11.25

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
