Answer:

Area = 867 meters

Step-by-step explanation:

You have a rectangle. This means opposite sides are equal. If you set these expressions equal to each other, you will get two equations with two unknowns, x and y. Next, solve the system of equations to find x and y. Then, use the values to find the length and width of the rectangle. Last, multiply length × width to find the area.

You are planning to put a new digital flat t.v on a wall that is 12ft long and 9ft high. the digital t.v has a diagonal of 72 in

Pie

Area of wall = 9 * 12 = 108 ft^2
Width of TV = x
Lenght = 2x
Diagonal of TV = 72 " = 6 ft

x^2+(2x)^2=6^2
x^2+4x^2=36
5x^2=35
x^2=36/5
x=sqrt(36/5)
Width = 2.68 ft.
Length = 2.68 * 5.36 = 14.36 ft^2
Area of wall - area of tv = 108 - 14.36 = 93.64 ft

Hey pls help !!! worth 25 points

Start with the point-slope form: $y-y_1 = m(x-x_1)$ .

Then you substitue in the slope and coordinates from the point:

$y-5 = 2(x-(-7))$

You don't do a lot of clean up to the form, with the exception of turning "minus negative 7" into "plus 7".

$y-5 = 2(x+7)$

Thar be yer answer!

7 . Cans of frozen OJ Total Cost ($) 1.25 1 2 2.50 3 3.75 4 5.00

aliina [53]

$\begin{gathered} x=\text{cans of frozen OJ} \\ f(x)=\text{Total cost(\$)} \\ f(x)=1.25x \\ f(1)=1.25(1)=1.25 \\ f(2)=1.25(2)=2.50 \\ f(3)=1.25(3)=3.75 \\ f(4)=1.25(4)=5.00 \end{gathered}$

Independent variable = x(Cans of frozen OJ)

dependent variable = y(total cost)
