Lily loves horses. Recently, a hurricane traveled through an area of Texas were there is a dense population of horses. Lily can get food for the horses for $0.30 per pound and medical supplies for $.40 per pound. An anonymous donor pledged $8,000 to the effort and has offered to send his plane which can hold 20,000 pounds of cargo to transport the food to the relief effort location. Let x = Number of pounds of Horse Food Let y = Number of pounds of Medical Supplies

Step-by-step explanation:

Let x = Number of pounds of Horse Food

Let y = Number of pounds of Medical Supplies

so

0.3x+0.4y=80001

x+y=200002  

multiply eqn 2 by 0.3 to eliminate x we have

0.3x+0.4y=8000  

0.3x+0.3y=6000

-0+0.1y=2000

0.1y=2000

y=2000/0.1

y= 20000

put y=2000 in eqn 2

x+20000=20000

x=20000-20000

x=0

its quite unfortunate that for her to maximize the opportunity and the money she has to carry 20,000 pounds of only  Medical Supplies

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
