Which statement best describes the graph of 2x−5y=−25 and the graph of y=52x+5?

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

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

What is the measure of angle x? answer
