Wich graph is the result of the reflection f(x) =1/4(8)^x across the y axis and then across the x- axis
Snowcat [4.5K]

Answer:

I assume that the function is:

f(x) = \frac{1}{4}*8^x

Now let's describe the general transformations that we need to use in this problem.

Reflection across the x-axis:

For a general function f(x), a reflection across the x-axis is written as:

g(x) = -f(x)

Reflection across the y-axis:

For a general function f(x), a reflection across the y-axis is written as:

g(x) = f(-x)

Then a reflection across the y-axis, and then a reflection across the x-axis is just:

g(x) = -(f(-x)) = -f(-x)

In this case, we have:

f(x) = \frac{1}{4}*8^x

then:

g(x) = -f(-x) =  -\frac{1}{4}*8^{-x}

Now we can graph this, to get the graph you can see below:

What is the value of x?<br>x=____​
Setler79 [48]
The answer is x = 6

To solve this you would use the pythagorean theorem which is a^2 + b^2 = c^2

In this problem a = x b = 8 and c = 10

You would then square these numbers
x^2 + 64 = 100

Next, you would subtract 64 from both sides.

x^2 = 36

All that’s left is the find the square root, which is x = 6.

So, therefore, you’re answer is x = 6

13. The length of a room is 4.5 feet longer than the width, w, of the room. Write an expression that represents the perimeter of
Naddik [55]

Step-by-step explanation:

length = 4.5 + w

width = w

perimeter means add all of the 4 sides

(4.5 + w) + (4.5 + w) + w + w

9 + 4w = answer

(3x-1)+31+90=180<br> Find x
AysviL [449]

<h2> SOLVE FOR X</h2>

ANSWER:

<h3> x = 20</h3>

  • <u>Add −1 and 31 to get 30.</u>

\large\color{orange}{ \tt{3x+30+90=180}}

  • <u>Add 30 and 90 to get 120.</u>

\large\color{orange}{ \tt{3x+120=180}}

  • <u>Subtract 120 from both sides.</u>

\large\color{orange}{ \tt{3x=180−120}}

  • <u>Subtract 120 from 180 to get 60.</u>

\large\color{orange}{ \tt{3x=60}}

  • <u>Divide both sides by 3.</u>

\large\color{orange}{ \tt{x=60/3}}

  • <u>Divide 60 by 3 to get 20.</u>

\large\color{orange}{ \tt{x = 20}}

Hope It's Help
