On the graph below, draw any line with a slope of *positive* 2 and draw any line with a slope of *negative* 2.
Elenna [48]

Refer to the image for the graph of the lines.

The common form of the equation of a line is y = mx + c, where m is the slope of the line and c is a constant.

We need to draw any line with a slope m = 2, and

another line with a slope m = -2.

Disclaimer: Let us assume that the constant c = 0.

Then the equation to the line with a slope of "positive" 2 is given by

y = 2x

Then the equation to the line with a slope of "negative" 2 is given by

y = -2x

Refer to the attached image for the graph of the lines with the slope of "positive" 2 and "negative" 2.

f: green line indicates a line with a slope of "positive" 2.

g: blue line indicates a line with a slope of "negative" 2.

in the three stacks of books there are 15 books, 9 books and 9 books if the books were rearranged so that the stack had the same
zepelin [54]

Answer:

<u>There would be 11 books in each stack, to have the same number.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Books in stack 1 = 15

Books in stack 2 = 9

Books in stack 3 = 9

2.  If the books were rearranged so that the stack had the same number of books how many books would be even?​

Total books = Books in stack 1 + Books in stack 2 + Books in stack 3

Total books = 15 + 9 + 9

Total books = 33

Total books/Number of stacks = Number of books per stack to be the same

33/3 = Number of books per stack to be the same

<u>Number of books per stack to be the same = 11</u>

△ABC is the image of △XYZ after a sequence of rigid transformations.
Korvikt [17]

Answer:

  D. ∠B≅∠Y, ∠A≅∠X, ∠C≅∠Z

Step-by-step explanation:

Corresponding angles are in the same order in both triangle names. That is, the corresponding angles are ...

  (A, X), (B, Y), (C, Z)

Rigid transformations do not change any angles, so the angles of the image are the same as the corresponding angles of the original.

  ∠A≅∠X, ∠B≅∠Y, ∠C≅∠Z . . . . . matches selection D
