Answer:

3x - 48y +5z = 0

Step-by-step explanation:

3x + 4x +7y +5z = 4x + 55y

Combine like terms

7x+7y+5z = 4x+55y

Subtract 4x from each side

7x -4x+7y+5z = 4x-4x+55y

3x +7y +5z = 55y

Subtract 55y from each side

3x +7y - 55y +5x =0

3x - 48y +5z = 0

(25 points) Ricardo wants to mix 1 part yellow paint to 3 parts blue paint to make a certain shade
Lapatulllka [165]

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


Let me know if you have any questions and I hope this helps! :)

Consider the following relation.
Jet001 [13]

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)
