When looking at a function graph, which value determines whether a graphed relation is a function or not? Domain or Range? Explain why.

Answers

Answer 1

Answer: It would be the domain, you can only have a unique y-value for each x, this is called the vertical line test. You can have the same y values for other points of y but not for the same point of x.

${y}^(6)$

Step-by-step explanation:

$\frac{ {y}^( - 7) }{ {y}^( - 13) }$

To solve the expression we use the rules of indices

Since the bases are the same and are dividing we subtract the exponents

That's

$\frac{ {a}^(x) }{ {a}^(y) } = {a}^(x - y)$

So we have

$\frac{ {y}^( - 7) }{ {y}^( - 13) } = {y}^( - 7 - - 13) = {y}^( - 7 + 13)$

We have the final answer as

${y}^(6)$

Wendy is arranging books on the bookshelves in the school library. The total number of books she arranges is given by the equation b = 12r, where b is the total number of books and r is the number of rows. Each row contains the same number of books.If Wendy arranged 16 rows, she arranged a total of
books.

Answers

Given:
b = 12r
where:
b = represents the total number of books
12 = number of books per row
r = number of rows

If Wendy arranged 16 rows, she arranged a total of ___ books.

b = 12r
b = 12(16)
b = 192 total number of books arranged.

you would do 16x12 which is 192

Three copies of a triangle were rotated and positioned as shown. Which statement is always true about the angles in the figure?a. Angle a and angle b form a right angle
b. Angle a, angle b, and angle c, form a straight angle.
c. angle a, angle b, and angle c from a acute angle.
d. Angle a and angle c form a right angle

Answers

If the above image is the supposed image for this problem, then,

B. Angle A, Angle B, and Angle C, form a straight angle.

A straight angle is 180°. C A B found in the middle of the picture forms the 180° straight angle.

Right angle is an angle which is equivalent to 90°
Acute angle is an angle which has less than 90°

As I can observe, the three triangles have two equal sides and two equal angles. These triangles are identified as isosceles triangles.
