50 cm = 1/2 m
3 m ÷ 1/2 m = 6
It will take him six days.
Answer:
The equations that represent the reflected function are
![f(x)=5(\frac{1}{5})^{-x}](https://tex.z-dn.net/?f=f%28x%29%3D5%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7B-x%7D)
![f(x)=5(5)^{x}](https://tex.z-dn.net/?f=f%28x%29%3D5%285%29%5E%7Bx%7D)
Step-by-step explanation:
The correct question in the attached figure
we have the function
![f(x)=5(\frac{1}{5})^{x}](https://tex.z-dn.net/?f=f%28x%29%3D5%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7Bx%7D)
we know that
A reflection across the y-axis interchanges positive x-values with negative x-values, swapping x and −x.
therefore
![f(−x) = f(x).](https://tex.z-dn.net/?f=f%28%E2%88%92x%29%20%3D%20f%28x%29.)
The reflection of the given function across the y-axis will be equal to
(Remember interchanges positive x-values with negative x-values)
![f(x)=5(\frac{1}{5})^{-x}](https://tex.z-dn.net/?f=f%28x%29%3D5%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7B-x%7D)
An equivalent form will be
![f(x)=5(\frac{1}{5})^{(-1)(x)}=5[(\frac{1}{5})^{-1})]^{x}=5(5)^{x}](https://tex.z-dn.net/?f=f%28x%29%3D5%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7B%28-1%29%28x%29%7D%3D5%5B%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7B-1%7D%29%5D%5E%7Bx%7D%3D5%285%29%5E%7Bx%7D)
therefore
The equations that represent the reflected function are
![f(x)=5(\frac{1}{5})^{-x}](https://tex.z-dn.net/?f=f%28x%29%3D5%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7B-x%7D)
![f(x)=5(5)^{x}](https://tex.z-dn.net/?f=f%28x%29%3D5%285%29%5E%7Bx%7D)
3(2a-5) = 12-7a
6a-15=12-7a
6a+7a=12+15
13a= 27
27=3c-3(6-2c)
27=3c-18+6c
27+18=3c+6c
45=9c
C=45/9
C=5
6c-8-2c=-16

Q1) £16.50 x 1.12 = £18.48
Q2)
2+9+1= 12
3h 33m = 213m
213/12 = 17.75
2x17.75 = 35.5 (music)
9x17.75 = 159.75 (films)
1x17.75 = 17.75 (books)
So it’s 159.75 minutes for the films to download
