Given that the elevator can only hold 4 people and that "people" could be either men "M" or woman "W", the possible combinations are as follows
WWWW = 0 men, 4 women = (0,4)
MWWW = 1 man, 3 women = (1,3)
MMWW = 2 men, 2 women = (2,2)
MMMW = 3 men, 1 woman = (3,1)
MMMM = 4 men, 0 woman = (4,0)
Answer:
17/7, y = 21 * (17/7), 51
Step-by-step explanation:
so to find what x is, we need to find how much it rises in 1 minute. we do that by dividing 17 by 7. we then see that we want to find how much is it filled in 21 minutes. we then multiply (17/7) by 21 to find the y which is 51
Answer:
y = x - 4
Step-by-step explanation:
equation of a line can be expressed as
(x - x1)/(x2 - x1) = (y - y1)/(y2 - y1)
(x - 5)/(10 - 5) = (y - 2)/(-3 - 2)
cross multiplying,
-5(x - 5) = 5(y - 2)
clearing the parentheses
-5x + 10 = 5y - 10
hence,
5y = 5x - 20
y = x - 4
