An elevator descends at a constant rate of speed from the top floor to the first floor of an office building. The equation below represents y, the height in feet of the elevator after x seconds. y=-5x +250
a. What is the y-intercept of the line represented by the equation?
b. What does the y-intercept represent in relation to the elevator?
c. What is the x-intercept of the line represented by the equation?
d. What does the x-intercept represent in relation to the elevator?
A second elevator in the same office building travels from the top floor to the first floor at a rate twice that of the first elevator.
e. Write an equation that can be used to represent y, the height in feet of the second elevator after x seconds.

ok

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
