Take -920/360 = -2.55555
Take the fraction part -0.5555555 * 360 = -200
The positive of that would be 160 degrees
The solution to this equation is x = 0 or x = 1
To find the solution, you use Desmos and enter x+2 in both one and 2^x+1 in box two. It will graph the lines for you and you take the x-coordinate of the two places where the lines overlap, and they overlap at (0,2) and (1,3).
Answer:
we need the linear graph ._.

- Layla charges $2 per day, plus a sign-up fee of $3. Notice the sign-up fee represents a fixed value, that's gonna be the constant form of the function. And $2 is the ratio of change of the function, because it a cost per day.
- Sam charges $3 per day, without extra fee. So, the ratio of change of this function is $3, and it doesn't have a constant term.
According to the given information, the linear function for Layla is:
![f(x)=2x+3](https://tex.z-dn.net/?f=f%28x%29%3D2x%2B3)
Notice that the constant ratio of change is coefficient of the independent variable, that is, because that variable represents days, and each charges $2.
On the other hand, the linear function for Sam is:
![g(x)=3x](https://tex.z-dn.net/?f=g%28x%29%3D3x)
As we said before, this expression doesn't have any constant term, because the charges are flate $3 per day, it's just that rate.
Now, to find the number of days needed to both Layla and Sam earn the same money, we just have to solve the equation ![f(x)=g(x)](https://tex.z-dn.net/?f=f%28x%29%3Dg%28x%29)
![2x+3=3x\\3=3x-2x\\x=3](https://tex.z-dn.net/?f=2x%2B3%3D3x%5C%5C3%3D3x-2x%5C%5Cx%3D3)
Therefore, on day three they are gonna earn the same amount of money.
Answer:
maybe 220/440?
