Answer:
y= (C -Ax)/B
x= (C -By)/A
Step-by-step explanation:
Ax+ By = C
solve for y
Subtract AX from each side
Ax+ By - Ax = C-Ax
By = C -Ax
Divide by B
By /B= (C -Ax)/B
y= (C -Ax)/B
solve for x
Subtract By from each side
Ax+ By - By = C-By
Ax = C -By
Divide by A
Ax/A= (C -By)/A
x= (C -By)/A
Answer:
In this problem, we are given the following functions:
and its inverse function:
First of all, we want to calculate 
. This can be obtained by substituting
x = 2
into f(x). Doing so, we find:
Then we want to calculate 
. We can do it by substituting
x = 1
into 
. Doing so,
Then we want to calculate 
, which can be found by calculating f(2) and then using it as input for 
We know that
f(2) = 1
Therefore,
Then we want to calculate 
, which can be calculated by plugging
x = -2
into . Doing so,
Then we want to calculate 
; by substituting
x = 4
into f(x), we find
Finally, we want to find 
We know already that
So we have:
<span>(x^2-4x-6) factors into:</span>
(x -5.1623) (x+1.1623)
Therefore x = 5.1623 and x = -1.1623
(4x^2-8x-2) <span>factors into:
(x -2.2247) * (x +2.2474)
</span>
Therefore x = 2.2247 and x= -0.22474
