in the empire state building, one elevator leaves the 3rd floor and goes up at a speed of 2 floors per second. another elevator leaves the 59th floor at exactly the same time and goes down at the same speed.
a) if the two elevators do not stop, how long will it take them to pass each other?

b) at what floor will the elevators pass each other?

A) 14 seconds

B) 31st floor

Step-by-step explanation:

First one:

3 + 2s

Second one:

59 - 2s

3 + 2s = 59 - 2s

4s = 56

s = 14

3 + 2(14)

31

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
