**Answer:**

A) horizontal shift right 6

i) reflection over the x axis

E) vertical strech by 1/2

D) vertical shift up 5

**Step-by-step explanation:**

f (x) = -1/2 . 4 ^ (x - 6) +5

fx=−1/24^(x−6)+5

y=−1/2 4^(x−6)+5

ok

the negative makes a reflection over x-axis

vertical stretch by 1/2

+5= up 5 vertically

(x-6) makes it go right 6

**Answer:**

** the download cost for a song is $1 and $11 for a movie **

**Step-by-step explanation:**

According to the questions, the following equations are as follows:

Let us assume the song be x

And, the movies be y

So,

20x + 13y = $163.........(i)

13x + 13y = $156........(ii)

Now solve substract second equation from the first equation

7x = $7

x = $1

And the y value is

20 + 13y = $163

13y = $163 - $20

13y = $143

y = $11

Hence,** the download cost for a song is $1 and $11 for a movie **

Yes. 4/1 is the same as 4.

Any number divided by 1 is itself. So 4/1 = 4
