Answer:
4 cans.
Step-by-step explanation:
There are 32 ounces in 1 quart. So to find exactly how many ounces needed you would multiply 32 by 3.
32 x 3 = 96
96 / 24 = 4
Which would give you the need to buy 4 cans
Answer:
![f^{-1}(x)=2\pm\sqrt{x-3}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D2%5Cpm%5Csqrt%7Bx-3%7D)
Step-by-step explanation:
we have
![y=(x-2)^2+3](https://tex.z-dn.net/?f=y%3D%28x-2%29%5E2%2B3)
step 1
Exchange the variables (x for y and y for x)
so
![x=(y-2)^2+3](https://tex.z-dn.net/?f=x%3D%28y-2%29%5E2%2B3)
Isolate the variable y
step 2
![x=(y-2)^2+3](https://tex.z-dn.net/?f=x%3D%28y-2%29%5E2%2B3)
subtract 3 both sides
![(y-2)^2=x-3](https://tex.z-dn.net/?f=%28y-2%29%5E2%3Dx-3)
step 3
square root both sides
![y-2=\pm\sqrt{x-3}](https://tex.z-dn.net/?f=y-2%3D%5Cpm%5Csqrt%7Bx-3%7D)
step 4
Adds 2 both sides
![y=2\pm\sqrt{x-3}](https://tex.z-dn.net/?f=y%3D2%5Cpm%5Csqrt%7Bx-3%7D)
step 5
Let
![f^{-1}(x)=y](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3Dy)
![f^{-1}(x)=2\pm\sqrt{x-3}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D2%5Cpm%5Csqrt%7Bx-3%7D)
Answer: C
Step-by-step explanation:
It is C because you are adding money to something you already have, hence positive integer
