Question

1.)

The caterer for your class picnic charges $1 for each hotdog and $2 for each hamburger. You have $48 to spend. Write a model that shows the different numbers of hot dogs and hamburgers that you could purchase...

2.) Airplane landing: An Airplane's altitude is 100 feet as it is descending for a landing on a runway whose touchdown point is 5000 feet away. Let the x-axis represent the distance on the ground and the y-axis represent the airplane's altitude.
WHAT IS THE SLOPE OF THE AIRPLANE'S DESCENT????

3.) WRITE AN EQUATION of the line that follows the path of the airplane's descent.

Answer 2

But Ms.Sue I need help with 2 and 3 please

Answer 3

since the plane descends 100 feet as it travels 5000 feet, clearly the slope is

-100/5000 = -0.02

so, since y=100 when x=0,

y = 100-0.02x

Note that when x=5000, y = 0, and we have touchdown.

Answer 4

THankyou Mr.Steve!
