A motorcycle travels 15 km west in an hour. The motorcycle then travels 35 km east in another hour. If east is taken as the positive direction, what is the velocity of the motorcycle?

10 km/h
50 km/h
–10 km/h
–50 km/h

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
