What’s it asking? What the question
For one cup of sugar, you would use 1 4/5 cups of flour
Answer:
-3
Step-by-step explanation:
Simplify the following:
(-9 (-5) - 9)/(-12)
-9 (-5) = 45:
(45 - 9)/(-12)
| 3 | 15
| 4 | 5
- | | 9
| 3 | 6:
36/(-12)
The gcd of 36 and -12 is 12, so 36/(-12) = (12×3)/(12 (-1)) = 12/12×3/(-1) = 3/(-1):
3/(-1)
Multiply numerator and denominator of 3/(-1) by -1:
Answer: -3
It’s 48 because you need 3, 1/3 cups to make 1 full cup so 3 times 16 is 48!
![\displaystyle\int e^{-x}\,\mathrm dx](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cint%20e%5E%7B-x%7D%5C%2C%5Cmathrm%20dx)
You probably know that the antiderivative of
![e^x](https://tex.z-dn.net/?f=e%5Ex)
is simply
![e^x](https://tex.z-dn.net/?f=e%5Ex)
. So to get something that resembles this form, let
![u=-x](https://tex.z-dn.net/?f=u%3D-x)
. Then
![\mathrm du=-\mathrm dx](https://tex.z-dn.net/?f=%5Cmathrm%20du%3D-%5Cmathrm%20dx)
, or
![-\mathrm du=\mathrm dx](https://tex.z-dn.net/?f=-%5Cmathrm%20du%3D%5Cmathrm%20dx)
.
Now the integral is
