Answer:

Step-by-step explanation:

Division by zero is undefined, so the only restriction on the domain, the values of x is that x cannot equal 9. So the domain is all real numbers except 9. Or in interval notation

x=(-oo,9),(9,+oo)

Answer:

All real numbers

Step-by-step explanation:

y = (x+1)(x-9)

y = x² - 8x - 9

There are no asymptotes, restrictions of x, or holes.

Find the ordered pairs that solve the equation y=12
Rufina [12.5K]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

y = 0.5x

when x = 12

y = 0.5 · (12)

y = 6

when x = 0

y = 0.5(0)

y = 0

when x = 8

y = 0.5(8)

y = 4

when x = 12

y = 0.5(12)

y = 6

Thus, the table is completed such as:

x             y

0             0

8             4

12           6

Therefore, the ordered pairs that complete the equation y = 0.5 x are:

  • (0, 0)
  • (8, 4)
  • (12, 6)

The graph of the equation is attached below.

A display case for the artifact is in the shape of a cube. Each side of the display case is three times longer than the width ww
Katena32 [7]
A cube is a 3d object bounded by  6 square faces. 

Each side of the display case is 3 times longer than the width of the artifact.

width of the artifact = w
side of the cube = 3w

<span>a. Write an expression for the volume of the case.
 volume of a cube is the measure of its side raised to the power of 3.

Volume = (3w)</span>³

<span>Volume = 27w</span>³<span>
