Okay so 300 meters per minute and he ran 8 minutes..
300x8=2400
He still had 600 left to go...
2400+600=3,000
He had to run three times longer than Eric...
3000/3=1000
Does that make sense?
Answer:
303
Step-by-step explanation:
I believe this is correct but I need to know the supplement.
X=7/2 which is equal to 3.5
First move the 4y to the right and the 1 to the left:
4y=5x-1
Then divide everything by 4:
y=5/4 x - 1/4
(4,5)(2,1)
slope = (1 - 5) / (2 - 4) = -4/-2 = 2
(-2,3)(-4,4)
slope = (4 - 3) / (-4 - (-2) = 1/(-4 + 2) = -1/2
2 and -1/2 are negative reciprocals of each other....therefore, ur lines are perpendicular <==
