Luis, using appropriate safety precautions, fires a .22 caliber gun directly into the sky above him. The bullet travels at a speed of 1200 feet per second. The following equation gives the height of the bullet at any point in time: H (height) = -16t2 + 1200t, where t is the number of seconds; t = 0 is the instant when the gun is fired.
How long will the bullet be in the air?

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.

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21

-7 + ? = 21

-7 + 28 = 21
