Hello!
When adding matrices you add the numbers that are in the same position
1 + 4 = 5
0 + 1 = 1
3 + 7 = 10
The answer is (5 1 10)
Hope this helps!
23=4w-13
First add 13 to both sides.
36=4w
w=9
Hope this helps!
Answer: -10h
I just put it into the calculator
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.
