Given:

The vertices of the rectangle ABCD are A(0,1), B(2,4), C(6,0), D(4,-3).

To find:

The area of the rectangle.

Solution:

Distance formula:

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using the distance formula, we get

AB=\sqrt{(2-0)^2+(4-1)^2}

AB=\sqrt{(2)^2+(3)^2}

AB=\sqrt{4+9}

AB=\sqrt{13}

Similarly,

BC=\sqrt{(6-2)^2+(0-4)^2}

BC=\sqrt{(4)^2+(-4)^2}

BC=\sqrt{16+16}

BC=\sqrt{32}

BC=4\sqrt{2}

Now, the length of the rectangle is AB=\sqrt{13} and the width of the rectangle is BC=4\sqrt{2}. So, the area of the rectangle is:

A=length \times width

A=\sqrt{13}\times 4\sqrt{2}

A=4\sqrt{26}

A\approx 20

Therefore, the area of the rectangle is 20 square units.

2x - 2y = 6 3x + 2y = 9 Solve the system of equations. A) x = 0, y = 3 B) x = 3, y = 0 C) x = 1, y = -2 D) x = -2, y = 1 E) x =

<h2>Answer:</h2>

There are 2 ways to solve this system: by elimination or by graphing. I will solve it by elimination. First will solve for x.

2x - 2y = 6\\3x + 2y = 9\\\\5x = 15\\\\x = 3\\

Now we will solve for y using what we got for x.

2(3) - 2y = 6\\\\6 - 2y = 6\\\\-2y = 0\\\\y = 0

Solution:

A: (0, 3)

The population of a small town in 1990 was 1,200 people, and the population in 2000 was 2,700 people. Let x represent the number
zheka24 [161]
Well... looking at how to question is defining things.....i think this is a multiple choice question.....

Given:
"y" represents the population
"x" represents the number of years
duration = 2000 - 1990 = 10 years
population increase = 2700 - 1200 = 1500
Now,
<u></u><u>It says linear equation........</u><u>, So, we have to assume that every ten years the population increases by a fixed </u><u>amount that is 1500 people every 10 years.</u><u />

Now, 
Every 10 years, the population increases by 1500
Every 1 year , the population increases by 1500 / 10 
                                                               = 150

Now,
The equation in determining the population is:

y = 150x + 1200
