I am pretty sure it's 44 degrees.
Answer:
![f^{-1} = \frac{x-1}{2}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%3D%20%5Cfrac%7Bx-1%7D%7B2%7D)
Step-by-step explanation:
![f(x) = 2x+1](https://tex.z-dn.net/?f=f%28x%29%20%3D%202x%2B1)
<em>Replace it with y</em>
![y = 2x+1](https://tex.z-dn.net/?f=y%20%3D%202x%2B1)
<em>Exchange the values of x and y</em>
![x = 2y+1](https://tex.z-dn.net/?f=x%20%3D%202y%2B1)
<em>Solve for y</em>
![x = 2y+1](https://tex.z-dn.net/?f=x%20%3D%202y%2B1)
<em>Subtracting 1 from both sides</em>
![2y = x-1](https://tex.z-dn.net/?f=2y%20%3D%20x-1)
<em>Dividing both sides by 2</em>
![y = \frac{x-1}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7Bx-1%7D%7B2%7D)
<em>Replace it by </em>![f^{-1}](https://tex.z-dn.net/?f=f%5E%7B-1%7D)
So,
![f^{-1} = \frac{x-1}{2}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%3D%20%5Cfrac%7Bx-1%7D%7B2%7D)
Answer:
80x
Step-by-step explanation:
If you pay 80 a month then to find the total you have paid after any number of months you would multiply amount times time which in this case is 80
a constant is the a number on its own so in this case there would be none
a coefficient is the number in front of a variable. Since the equation is 80x the coefficient is 80
Break down the words into an equation:
(x+7)/(x+3) + (x-4)/3
Answer:c. Y=(x-3)^2-2
Step-by-step explanation: y=(x-3)^2-2
Y=x^2-6x+7
