Question

Hot dogs and Hamburgers:
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 1

Can't help. You will need to post one question at a time. Besides, we don't do homework for you. We help, not giving out answers sorry.

Answer 2

1. d+2h=48
2. So when the plane starts to descend at 100 feet, its at 0 on the X axis, so your point is (0, 100). It's touchdown point is 5000 feet away, so it will be at 5000 on the x axis and 0 on the y axis, so your point is (5000, 0). Now you have two points so you can find the slope using the slope formula, (y2-y1) / (x2-x1), so that would be (0-100) / (5000-0), which gives you -100/5000, or -1/50. The y intercept is 100 because that's what y was when x was 0. Now you have the slope and the y intercept, so go ahead and put in into slope-intercept form, y=mX-b when m=the slope and b=the y intercept, so you have
y=-1/50x+100. Hope I helped!!!!!

3. Sorry cant help with that one!!
