Ms. Pendleton’s bedroom is a shape of a rectangle. The width of the room is 16 feet and length is four more feet than the width.

QveST [7]

Answer:

The answer to your question is Perimeter = 64 ft

Step-by-step explanation:

Data

width = 16 ft

length = width + 4 ft

Perimeter = ?

Process

1.- Calculate the length

Length = 14 + 4 = 18 ft

2.- Look for the formula of the perimeter

Perimeter = 2(length) + 2(width)

3.- Substitution

Perimeter = 2(18) + 2(14)

4.- Simplification

Perimeter = 36 + 28

5.- Result

Perimeter = 64 ft

Which explains whether or not the function represents a direct variation?

s2008m [1.1K]

Answer:

The function represents a direct variation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a linear direct variation the line passes through the origin and the constant of proportionality k is equal to the slope m

Let

$A(0,0)$ ------> the line passes through the origin

$B(2,10)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=10/2=5$

$C(4,20)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=20/4=5$

$D(6,30)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=30/6=5$

$E(8,40)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=40/8=5$

The value of k is equal in all the points of the table and the line passes through the origin

therefore

The function represents a direct variation

the equation of the direct variation is equal to

$f(x)=5x$
