Answer:
6 pints of blue
Step-by-step explanation:
note- 8 pints = 1 gallon
Original ratio- 3 parts blue to 1 part yellow ( 3b:1y)
This will make 4 pints if we say that 1 part can be one pint
Ricardo needs 8 pints
Divide the amount needed by how much one portion will make
8/4= 2
Multiply original ratio by 2 to see how many pints of each he’ll need for his new amounts
1y*2= 2 pints yellow paint
3b*2=6 pints of blue paint
So to make 8 pints of green with 3 parts blue to 1 part yellow Ricardo will need 6 pints of blue paint

Answer:
(0,-1),(1,0),(2,1),(3,2)
Step-by-step explanation:
We are given that a relation
y=x+1y=x+1
We have to find the four points contained in the inverse
The given function is linear function
Therefore,
Domain of function=R
Range of function=R
x=y-1x=y−1
Now, replace x by y and y replace by x
y=x-1y=x−1
Now, substitute y=f^{-1}(x)=f
−1
(x)
f^{-1}(x)=x-1f
−1
(x)=x−1
It is linear function and defined for all real values.
Substitute x=0
f^{-1}(0)=-1f
−1
(0)=−1
Substitute x=1
f^{-1}(1)=1-1=0f
−1
(1)=1−1=0
f^{-1}(2)=2-1=1f
−1
(2)=2−1=1
f^{-1}(3)=3-1=2f
−1
(3)=3−1=2
Therefore, four points contained in the inverse (0,-1),(1,0),(2,1) and (3,2)
