Answer:

2800m

Step-by-step explanation:

Assumption:

Start point from which Percy Cod walks is "x"

If he walks around a perimeter that is the shape of a rectangle,

Length of area = L = 1000m

Width of area = W = 400m

Distance around the rectangle = D = 2 * (L + W)

D = 2 * (400+1000)

D = 2 * 1400

D = 2800m

Answer:

-4

Step-by-step explanation:

There are many methods to solve this system of equations.

I will use the elimination method.

First step:

Multiply the first equation by -2

2(2x-3y) = -14(-2)

-4x + 6y = 28

Multiply the second equation by 3 so you can eliminate the y term

3(3x-2y) = -6(3)

9x-6y = -18

Second step: Add the equations vertically(Basically adding like terms)

-4x+6y = 28

     +

9x - 6y = -18

5x = 10

Third step: Solve for x

\frac{5x}{5}  = \frac{10}{5}

x = 2

Substitute the x-value into any of the original equation to get the y value

3(x) - 2y = -6

3(2) - 2y = -6

6 - 2y = -6 (Since we are solving for y, it will be isolated and we will move 6 to the other side)

-2y = -6 - 6(Moving 6 to the other side makes it negative)

Solve for y by dividing by -2

\frac{-2y}{-2} = \frac{-12}{-2}

y = 6

So (x, y) = (2, 6)

Since the question is asking to subtract x and y

2-6 = -4

Solve the system of equations.
sasho [114]

Step-by-step explanation:

y = x² - 3x + 6

y = 2x + 6

y = y

x² - 3x + 6 = 2x + 6

x² - 5x = 0

x(x - 5) = 0

x = 0 and x = 5

y = 2x + 6 and y = 2x + 6

y = 2(0) + 6 and y = 2(5) + 6

y = 0 + 6 and y = 10 + 6

y = 6 and y = 16

(x1,y1) and (x2, y2) = (0,6) and (5,16)

Option → A

According to u.s. postal regulations, the girth plus the length of a parcel sent by mail may not exceed 108 inches, where by "gi
Pepsi [2]
Let x represent the side length of the square end, and let d represent the dimension that is the sum of length and girth. Then the volume V is given by
  V = x²(d -4x)
Volume will be maximized when the derivative of V is zero.
  dV/dx = 0 = -12x² +2dx
  0 = -2x(6x -d)
This has solutions
  x = 0, x = d/6

a) The largest possible volume is
  (d/6)²(d -4d/6) = 2(d/6)³
  = 2(108 in/6)³ = 11,664 in³

b) The dimensions of the package with largest volume are
  d/6 = 18 inches square by
  d -4d/6 = d/3 = 36 inches long
