(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 <==
The 10th term is dividing by 2 so you will get 0.03125, just round that number to what the directions says cuz i can’t see it.
hope this helps !
All we need to do is plug in the values and check.
15*60 + 10 * 20 ≥ 1100.
Is this statement true?
15 * 60 = 900
20 * 10 = 200
900+200 = 1100
Is the statement 1100≥1100 true?
Yes! So, (60, 20) is a solution because 1100 is greater than or equal to 1100.
