First make x the subject of the relation:-
f(x) = 2x - 4
2x = f(x) + 4
x = (f(x) + 4) / 2
Now replace x by the inverse f-1(x) and f(x) by x :-
f-1(x) = (x + 4) / 2
Answer:
y = 1 x = 3
the +1 at the end of the equation is the y intercept while the number with the x is the slope, since the slope is -1/3 take it as if it was rise/run. In other words since the rise is -1 you are going down 1 unit and the run is 3 you are going 3 units to the right & that's the path its going to be taking. So that makes the line cross the x axis at (0,3)
Answer: You should create number line since it's a inequality question, so it would make sense. But In my opinion I don't think you need to show your work unless it tells you to. So that's why I'm telling you that you can show work, which is by making a number line.

Remove the brackets
6 - t + 7 - t - 4 + t = 0
Eliminate the two opposite t because they cancel out to each other
6 + 7 - t - 4 = 0
Add and subtract
6 + 7 - 4 = 9
Thus:
9 - t = 0
Bring the 9 over to the 0 to isolate the -t
-t = 0 - 9
Calculate:
-t = -9
To get rid of the negative on the variable we have to divide it by -1 to make it positive bc negative divided by negative equals positive. Since we are dividing -1 to the -t we also have to divide -9 by -1.
t = 9
