[Part A]
company A ->  A=30m+13
company B ->  B=28m+15

A=company A
B=company B
m= number of mattresses

[Part B]
Price charged to clean 4 mattresses
company A= $133
company B= $127

Justification
A=30(4)+13                  B=28(4)+15
A=120+13                     B=112+15
A=133                           B=127

Company B would charge less. Even though the y-intercept is higher, the slope has a lower value which makes company A grow at a faster rate.

[Part C]
If you use company B instead of company A to clean 7 mattresses you will save 12 dollars.  The price to clean 7 mattresses with company A is 223 while company B costs 211.

Company A: A=30(7)+13=223
Company B: B=28(7)+15=211

GIVING BRAINIEST IF CORRECT!!<br><br> Factor x^4 - 16 completely
ioda

Answer:

(x^2 + 4)(x + 2)(x - 2)

Step-by-step explanation:

Hello!

We can use the difference of square method.

<h2>Difference Of Squares (DOS)</h2>

The formula for the DOS is (a + b)(a - b) = a^2 - b^2

It is a simple way to factor polynomials.

The criteria:

  • Has to begin and end with a perfect square
  • The operation has to be subtraction

<h3>Factor:</h3>
  • x^4 - 16

Begins with a perfect square (x² * x²) and ends with a perfect square (4 * 4)

  • (x^2 + 4)(x^2 - 4)

Warning! Watch out, there may be another DOS!

x^2 - 4 is another DOS

  • (x^2 + 4)(x + 2)(x - 2)

The x² + 4 is not a DOS because the operation is addition.

The final factored form is (x^2 + 4)(x + 2)(x - 2)

David bought a pizza for $12.74 and four medium drinks. Define a variable and write an expression to represent the total amount
SSSSS [86.1K]
You could say each drink is d. And we'll say the total is t. David got 4 drinks,

So... 12.74 + 4d = t

Hope this helps!

Help!!!i need it quick
Eddi Din [679]

Answer:

A linear function is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

An exponential equation is written as:

y = A*(r)^x

Where A is the initial quantity and r is the rate of growth.

If a and A are both positives, the similar characteristic of both types of functions is that as x increases, then the value of y will also increase. Then both functions are increasing functions.

They are different in how they increase, while a linear function increases at a constant rate, an exponential function increases slow at the beginning and really fast as x increases, as you can see in the image below where we compare the two types of functions, the green one is the linear function, and the blue one is the exponential function.
