Answer:
x=7
Step-by-step explanation:
8(1X/4 +12 - 1 x 1/2X)=82
8(X/4 +12-1 x 1/2 x X)=82
8(X/4+ 12 - 1/2x)=82
8 X x/4 + 96+8 X -x/2=82
2x +96 +8 X -x/2=82
2x +96+ 8(-1)/2=82
2x +96 -8x/2 =82
2x+96-4x=82
-2x+96=82
-2x=-14
x=7
plz like and rate thank you
Answer:
Step-by-step explanation:
12x+36 =8x+36+4x
12x+36= 12x+36
which means any value of x will work.
Since 79/100 can be written as 0.79
you can write 94 79/100 as 94.79
Given the function

The inverse of the function is calculated by changing f(x) to y and making x the subject of the formula as follows:

We now change back the variables to get the function in the form of inverse function as follows:

Comparing this with Talib's work, we can see that he is correct except for the last line where he did not change the variable y back to x.
Therefore, the last line of his work made his inverse not to be correct.
