I can:
find equivalent linear expressions,
for example: 1.2x + 1.3x + 0.2y + 0.1y = 2.5x + 0.3y
rewrite linear expressions in different ways, for example: X + 0.2x = 1.2x
solve problems with equations
solve problems with inequalities

Do u just plot the numbers on the graph like (1,

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?
