It would be 20 because if you estimate 53 you would get 50 so 50÷3 would be clase to 2 and then add 1 zero and you will get 20 so 20 is your answer. Hope this helped. ☺
Answer:
Both are inverse pairs
Step-by-step explanation:
Question 11
![g(x)= 4 + \dfrac{8}{5}x](https://tex.z-dn.net/?f=g%28x%29%3D%204%20%2B%20%5Cdfrac%7B8%7D%7B5%7Dx)
(a) Rename g(x) as y
![y = 4 + \dfrac{8}{5}x](https://tex.z-dn.net/?f=y%20%3D%204%20%2B%20%5Cdfrac%7B8%7D%7B5%7Dx)
(b) Solve for x :
![\dfrac{8}{5}x = y - 4](https://tex.z-dn.net/?f=%5Cdfrac%7B8%7D%7B5%7Dx%20%3D%20y%20-%204)
(c) Multiply each side by ⅝
![x = \dfrac{5}{8}(y - 4) = \dfrac{5}{8}y - \dfrac{5}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7B5%7D%7B8%7D%28y%20-%204%29%20%3D%20%5Cdfrac%7B5%7D%7B8%7Dy%20-%20%5Cdfrac%7B5%7D%7B2%7D)
(d) Switch x and y
![y = \dfrac{5}{8}x - \dfrac{5}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cdfrac%7B5%7D%7B8%7Dx%20-%20%5Cdfrac%7B5%7D%7B2%7D)
(e) Rename y as the inverse function
![g^{-1}(x) = \dfrac{5}{8}x - \dfrac{5}{2}](https://tex.z-dn.net/?f=g%5E%7B-1%7D%28x%29%20%3D%20%5Cdfrac%7B5%7D%7B8%7Dx%20-%20%5Cdfrac%7B5%7D%7B2%7D)
(f) Compare with your function
![f(x) = \dfrac{5}{8}x - \dfrac{5}{2}\\\\f(x) = g^{-1}(x)](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cdfrac%7B5%7D%7B8%7Dx%20-%20%5Cdfrac%7B5%7D%7B2%7D%5C%5C%5C%5Cf%28x%29%20%3D%20g%5E%7B-1%7D%28x%29)
f(x) and g(x) are inverse functions.
The graphs of inverse functions are reflections of each other across the line y = x.
In the first diagram, the graph of ƒ(x) (blue) is the reflection of g(x) (red) about the line y = x (black)
Question 12
h(x)= x - 2
(a) Rename h(x) as y
y = x - 2
(b) Solve for x:
x = y + 2
(c) Switch x and y
y = x + 2
(e) Rename y as the inverse function
h⁻¹(x) = x + 2
(f) Compare with your function
f(x) = x + 2
f(x) = h⁻¹(x)
h(x) and ƒ(x) are inverse functions.
The graph of h(x) (blue) reflects ƒ(x) (red) across the line y = x (black).
