2x-4=2x-2?
false

the answer is no
No, these are not equal because:-

2(x - 2) = 2*x - 2*2 = 2x - 4

2x - 2 is not equal to 2x - 4

Answer: Not equal

My math teacher is giving me a question about the mean absolute deviation. I don't really get it. Some help please.

Answers

well, you didn't show the question but i can tell you this: first find the mean of the data set.
1) 1+2+3+4=10    10/4(amount of #)=2.5
then, subtract the mean from each number in the data set.
2) 1-2.5= -1.5; 2-2.5= -0.5; 3-2.5= 0.5; 4-2.5= 1.5
convert all these numbers to positive, then add them together.
3)1.5 + 0.5 + 0.5 +1.5 = 4
divide the total by the amount of # in the data set
4/4=1
the MAD in this case is 1.

Hope i helped!! :)


15x+1200=y what is the change in the total cost for each book printed? What is the cost to get started before any books are printed

Answers

The total cost before books are printed is $1200 (the constant).

The change to the total cost is the x, which is a variable, and can change depending on the amount of books printed.

Plug in a test point to find the region to be shaded

Answers

is there a picture we can use to understand this?

Answer:

Answers will vary. For example, plugging in the test point (0, 0):

x + y ≤ 900

0 + 0 ≤ 900

0 ≤ 900

The test point (0, 0) holds true for the inequality.

Anita has a collection of postage stamps from different countries. She has one book that contains 35 stamps. She has a second book that has 7 stamps on each page. the equation below can be use to find t, the total number of postage stamps Anita has if the second book has p pages.t=35+7p

How many postage stamps does Anita have in all if the second book has 14 pages

Answers

Anita has 133 postage stamps with 2 books having 35 stamps in the first book and 14 page in second book with 7 stamp on each page of book.

What is equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign. The point-slope form, standard form, and slope-intercept form are the three main types of linear equations. a formula that expresses the connection between two expressions on either side of a sign. Typically, it has a single variable and an equal sign. Like this: 2x - 4 = 2. In the provided example, the variable x exists.

Here,

Anita has a collection of postage stamps from different countries. She has one book that contains 35 stamps. She has a second book that has 7 stamps on each page. the total number of postage stamps t Anita has if the second book has p pages.

The given equation is,

t=35+7p

p=14

t=35+7*14

t=133

Anita has 133 postage stamps in total, with 35 stamps in the first book and 7 stamps per page in the second book, which has 14 pages.
