Answer:

-5x from both sides

Step-by-step explanation:

When converting an equation to slope-intercept form, you need to isolate the y. The first step in isolating the y is to remove 5x from both sides of the equation:

5x - y = 7

5x - 5x - y = 7 - 5x

-y = 7 - 5x

Now it's just -1y on one side of the equation.

Answer:

length = 200 m

width = 400 m

Step-by-step explanation:

Let the length of the plaing area is L and the width of the playing area is W.

Length of fencing around three sides = 2 L + W = 800

W = 800 - 2L ..... (1)

Let A is the area of playing area

A = L x W

A = L (800 - 2L)

A = 800 L - 2L²

Differentiate with respect to L.

dA/dL = 800 - 4 L

It is equal to zero for maxima and minima

800 - 4 L = 0

L = 200 m

W = 800 - 2 x 200 = 400 m

So, the area is maximum if the length is 200 m and the width is 400 m.

Solve the system using substitution.
miv72 [106K]

Substitution method is one of the ways to solve this system.

-5x+y=4 and 4x-4y=16.

First we will divide the second equation with number 4 and get

x-y=4 => x=y+4 than we will replace x in the first equation

-5(y+4)+y=4 => -5y-20+y=4 => -4y=4+20 => -4y=24 => y=-6

x-(-6))=4 => x+6=4 => x=4-6=-2    (x,y)=(-2,-6)

Good luck!!!
