Answers

Answer 1
Answer:

The magazine prices can be ( 3 $, 9 $ ) ,  ( 6 $, 6 $ ) and  ( 9 $, 3 $ )

Step-by-step explanation:

Ken paid $12 for two magazines.the cost of each magazine was a multiple of $3.

The multiples of 3 less than 12 are 3,6 and 9.

Let the price of magazine 1 be 3 $

            Price of magazine 2 = 12 - 3 = 9$

Let the price of magazine 1 be 6 $

            Price of magazine 2 = 12 - 6 = 6$

Let the price of magazine 1 be 9 $

            Price of magazine 2 = 12 - 9 = 3$

So the magazine prices can be ( 3 $, 9 $ ) ,  ( 6 $, 6 $ ) and  ( 9 $, 3 $ )
Answer 2
Answer: WORK:
$12 ÷ 2 = $6

What is the area of this rectangle in square yards?

Answers

In the comment of the other answer, you said that the rectangle is 24 x 18 ft.

First, we have to find out how many square feet that is, and then we can convert it to square yards.

The area of a rectangle is the length multiplied by the width.

A = l x w
A = 24 x 18
A = 432 square feet

To find out how many square yards that is, we divide it by 3, because 1 yard is 3 feet.

432 ÷ 3 = 144

The area of a 24x18ft rectangle is 144 square yards.

How are a common denominator and a common multiple alike and different?

Answers

The Common Denominator is the bottom part of a fraction which has been matched to 2 or more fractions. For example 1/2 + 1/4 is easier if you use 2/4 + 1/4 = 3/4. You can also use it for 3/5 + 1 2/3 Becomes 3/5 + 5/3 (Improper fraction) and you change that to 9/15 + 25/15 = 34/15 = 2 4/15
A common denominator and common multiple are alike because they both go on the bottom portion of the fraction and in order to get the common denominator you need to find the common multiple of numbers.

They are different because they have different purposes and the common denominator stays the same and the common multiple is supposed to change both or one number.

Given the parent function of f(x) = x3, what change will occur when the function is changed to f(x) − 3?

Answers

For this case we have that the main function is given by:

We apply the following transformation:

Vertical displacements:

Assume k> 0

To graph y = f (x) - k, move the graph k units down.

For k = 3 we have:

Answer:

when the function is changed to f (x) - 3 the change that will occur is:

Vertical displacement 3 units down.
the function line will move down 3 units.
