Substitute the values of x and y into the expression -3x2 + 2y2 + 5xy - 2y + 5x2 - 3y2. Match that value to one of the numbers. What matches what I'm stuck 1. x = 0.5, y = -1/10 2. x = -1, y = -3 3. x =3/4 , y = 2/5 4. x = 0, y = 2.5 5. x = √2, y = √2 6. x = 2, y = -1 The answer thing. -1 9.17 14 -11.25 1.665 0.44

x = 2, y = -1  Answer = -1

x = 0, y = 2.5  Answer = -11.25

x = -1, y = -3   Answer = 14

x = 0.5, y = -0.1 (one tenths)  Answer = 0.44

x = 0.75 (three quarters), y = 0.4 (two fifths)  Answer = 1.665

x = 1.41 (sqareroot of 2), y = 1.41 (sqareroot of 2)  Answer = 9.17
