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

Ifigured out the question and i dont know what to put here

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling
