ANSWER:

<u>On solving equation, we get</u>

  • 3x - y = 12
  • 3x = 12 + y
  • x = 12 + y/3 ...(1)

<u>We have to find</u>,

  • 8^x/2^y
  • 2^3x/2^y
  • 2^3x - y

<u>Plugging the value of x</u>,

  • 2^3(12 + y/3) - y
  • 2^12 + y - y
  • 2^12
  • 4096

Hence, The value of 8^x/2^y is 4096.

Answer:

-1/3

Step-by-step explanation:

Use the formula, (y2 - y1)/(x2 - x1).  In this case, there is a negative slope.  

Start from point, (1, 9) and go to point (4, 8).  

Use the formula:

(y2 - y1)/(x2 - x1)

Y2 = 8

Y1 = 4

X2 = 9

X1 = 1

(8 - 9)/(4 - 1) = -1/3

Therefore, the slope is -1/3

The graph below shows the time Andrea spent reading one day. Write a few sentences to describe the relationship between the time
Alex777 [14]

Answer:

Step-by-step explanation:

Well, there are several  relationships you can describe.  As time increases how does number of pages  react?  Like does it increase or decrease.  Is it always increasing or decreasing by the same amount?  If it's not all the same how do different parts look different.  

There aren't any actual numbers, so you can't say specifically how they relate, like you can't say she read 5 pages a minute or something.

2(x+3)^2+2(y)^2=32 what is the center point of the circle and how long is the radius
spayn [35]

Answer:

  • center (-3, 0)
  • radius 4

Step-by-step explanation:

The standard form equation of a circle is ...

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . . . . center at (h, k), radius r

Divide your given equation by 2 to put it into standard form:

  (x +3)^2 +y^2 = 16

Comparing to the above, we see ...

  • h = -3
  • k = 0
  • r = √16 = 4

The center point of the circle is (-3, 0); the radius is 4 units long.
