Has anyone taken The Kangaroo Math test? Can someone pls tell me what/how to ACE it? (Whoever gives the best advice will be brainliest

Asequence is defined recursively using the formula f(n + 1) =f(n) - 5. which sequence could be

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?

What is the slope-intercept from of the equation y+5=4(x+8)?
