Match each linear equation to its slope and y-Intercept. slope:3/2 y-intercept 7/2
slope: 5/2 y-intercept 7/2
slope:1/5 y-intercept: 4/5
slope:1/5 y-intercept: 3
slope:-5 y-intercept: 4/5
2y-3x=7
5y- x= 15
-x+5y = 4
2y = 5x +7

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?
