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

What is the function rule for the line?

11Alexandr11 [23.1K]

So with these equations we need to find the y-intercept and the slope because:

y = mx+b

y = f(×)

b = y-intercept

m = slope (slope = rise/run, rise over run)

rise is y-axis
run is x-axis

The y-intercept is (0,-2)
So now we know that one of the answers must have -2 in it

b = -2

m= rise/run = -2/3

The answer is:

$f(x) = - \frac{2 }{3 } x - 2$
