The formula for an average of three numbers is (x+y+z)/3. So if V equals the average, then we find the formula
V = (x+y+z)/3
We are now looking for x. We can divide each of the variables in the parentheses by 3, making the formula
V = x/3 + y/3 + z/3
So now bring the unwanted variables to the same side as V.
V - y/3 - z/3 = x/3
Now multiply both sides by 3 to find x.
3V - y - z = x
x = 3V - y - z

Step-by-step explanation:
If we have a function f(x) and we want to compress its graph vertically c units then we must do the transformation
Where .
If we want to make a transformation that moves horizontally h units the graph of f(x) then we must do:
If the graph of f(x) shifts h units to the left
If the graph of f(x) shifts h units to the right.
If we want to make a transformation that moves vertically k units the graph of f(x) then we must do
If the graph of f(x) moves k units up
If the graph of f(x) shifts k units down
In this case
If the transformation vertically compresses the function by a factor of and moves the function 3 units to the right and 2 units up then the transformation is:
The function is:
I put this into good old Desmos since I couldn't figure it out by hand. So here is what I got.
BC= 30
