<h3>
Answer: Choice A) 10/27 cup flour</h3>
=======================================================
Work Shown:
3/5 cup water = 2/3 cup flour
15*(3/5) cup water = 15*(2/3) cup flour
9 cups water = 10 cups flour
9/27 cup water = 10/27 cup flour
1/3 cup water = 10/27 cup flour
In the second step I multiplied both sides by 15 to clear out the fractions. In the second to last step, I divided both sides by 27 so that it forms the fraction 9/27 which reduces to 1/3.
The answer is that f-1(3) = 7.
In order to find the answer, we first must find the inverse function. The f-1 indicates that we are looking for an inverse. To find any inverse, we first must switch the x and f(x) values. We then solve for the new f(x), which gives us the inverse.
f(x) = (2x - 2)/4 ----> Switch x and f(x)
x = (2f(x) - 2)/4 -----> Multiply both sides by 4
4x = 2f(x) - 2 ----0-> Add 2 to both sides
4x + 2 = 2f(x) ------> Divide both sides by 2
f-1(x) = (4x + 2)/2
Now that we have the inverse function, we can put in 3 and find the answer.
f-1(x) = (4x + 2)/2
f-1(3) = (4(3) + 2)/2
f-1(3) = (12 + 2)/2
f-1(3) = (14)/2
f-1(3) = 7
Answer:
A.It is a proportional relationship
Step-by-step explanation:
Because if you take each amount of dollars earned and divide it by each number of hours it gives you 12.5 every single time
You could make an equivalent fraction by multiplying both numbers by 2.
Answer:
x= 3/2 or x=1.5
Step-by-step explanation:
subtract 17 to the other side of the equation.
Next you divide both sides of the equation by 4.
You have your answer :)
