4. The graph below models the drainage. The x-axis is the time in hours, and the y-axis is the cubic feet of water in the trough(pipe).

What is the
rate of change?"

a) -50
b) 50
c) -200
d) 200

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

positive

step-by-step explanation:

the quadrant is facing upwards

2 apples

step-by-step explanation:

taking away equals subtraction. 6-4=2

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
