Answer:
f^-1(x) = The quantity of 3x plus 2, divided by 4.
Step-by-step explanation:
Given: f(x) = (4x -2)/3
Which is y = (4x - 2)/3
We have to find the inverse function f^-1 (x)
Replace x by y and y by x, we get
x = (4y - 2)/3
Now find the function y interms of x.
3x = 4y - 2
4y = 3x + 2
y = (3x + 2)/4
f^-1(x) = The quantity of 3x + 2, divided by 4.
Answer is D) f^-1(x) = The quantity of 3x plus 2, divided by 4.
Hope this will helpful.
Thank you.
Answer:
Step-by-step Simplifying
6 + -3x = 4 + -1x + -3 + -2x
Reorder the terms:
6 + -3x = 4 + -3 + -1x + -2x
Combine like terms: 4 + -3 = 1
6 + -3x = 1 + -1x + -2x
Combine like terms: -1x + -2x = -3x
6 + -3x = 1 + -3x
Add '3x' to each side of the equation.
6 + -3x + 3x = 1 + -3x + 3x
Combine like terms: -3x + 3x = 0
6 + 0 = 1 + -3x + 3x
6 = 1 + -3x + 3x
Combine like terms: -3x + 3x = 0
6 = 1 + 0
6 = 1
Solving
6 = 1
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
Answer:

Step-by-step explanation:
Find the mean:
Day 1: 2
Day 2: 1
Day 3: 4
Day 4: 5
Day 5: 0
Day 6: 7
Mean = 
This does not exceed a daily mean of 3.5 hours which was set by her mom as a guideline.
Therefore we can conclude that:
"Chawrdi complied with the guideline because the mean number of hours played is .
Answer: the person would have to visit a total of twelve times for it to add up to $48
Step-by-step explanation:
48-15=33
then divide the 33 by 3 and you get 11 plus the 15 dollar membership and visit will get u 12 visits for $48.
Answer:
0
Step-by-step explanation:
Approximately 0.2% of the apples will be more than three standard deviations above the mean size. In a bin of 100 apples, 0.2% of 100=0.2% apples, this rounds down to zero apples that size or larger. (In a bin of 500 apples, there could be one apple of that size.)
