Is (-1,7) a solution for the system of linear equations below? x + 2y = 13 and 3x - y
= -11
O
YES it is a solution for BOTH equations.
O
NO it is not because it is a solution for ONLY the equation x + 2y = 13
NO it is not because it is a solution for ONLY the equation 3x - y = -11
NO it is not a solution for NEITHER equation.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
