Answer:
y = - 3x -11
Step-by-step explanation:
(x₁ , y₁) = (-2 , -5) & m = -3
y - y₁ = m (x - x₁)
y - [-5] = (-3)(x -[-2])
y + 5 = (-3)(x + 2)
y + 5 = -3x - 6
y = -3x - 6 - 5
y = - 3x -11
If we let
x as the length of the pen
y as the width of the pen
The area is
xy = 2000
The perimeter is
P = 2(x+y)
From the area
y = 2000/x
Substituting
P = 2(x + 2000/x)
which is the equation used to find the least amount of fencing possible.<span />
Answer:
What our the points?
Step-by-step explanation:
If you know the points then you can find the domain of them. example (1,4)(2,9),(4,8)
The domain of these would be 1,2,4
Range is 4,9,8
Together it would take a total of 4 hours to completely fill the pool.
1760 divided by 4 equals 440. This is the amount of liters that the second pump will fill the pool in 4 hours, so 440 divided by four is the amount that the second pump will fill the pool in one hour. 440/4= 110.
Now we add 110 to 330 to get the hourly rate of both pumps filling the pool. 110+330=440.
1760/440 equals 4.
So it takes 4 hours for both pumps to fill the pool.
Hope this helps!
