Your inverse funtion would look like this:
f
−
1
(
x
)
=
−
x
7
−
4
7 . This would be your answer.
You're welcome ;)
Since x=8y, subsitute 8y for x in other equation
y=6x-11
y=6(8y)-11
y=48y-11
minus y both sides
0=47y-11
add 11 to both sides
11=47y
divide both sides by 47

subsitute taht for y to find x
x=8y




in (x,y) form
(x,y)
1 radian
because s= r × angle measurement in radian
we have s= arc , r = radian so we got the value
The quotients are equal because they both go in the same number of times. The second pair of quotients just have an extra 0 at the end which just changes the place value of the number.
