<span>Yes you're right.
The way to find out if functions are inverses of each other is to check
and see if their composite functions are equal to x. Also make sure the
functions are one to one functions.
(fog)(x)=f(g(x))=f(3/2x-9)
f(3/2x-9)=2/3(3/2x-9)+6
=(2/3)(3/2)x+(2/3)(-9/1)+6
=x-18/3+6
=x-6+6

You multiply 0.6 by 5x and 10 and you get 3x+6=-24. you then subtract 6 from both sides of the equation and you get 3x=-30. after that you divide both sides by 3 and you get x=-10. so the answer is B!
It looks like you want to evaluate
.. 8j -k +14
for (j, k) = (0.25, 1).
Put the numbers where the letters are. If you cannot do the math, let your calculator do it.
.. 8*0.25 -1 +14
.. = 2 -1 +14
.. = 1 +14
.. = 15
The value of the expression is 15 at (j, k) = (0.25, 1).
95% fall within 2 standard deviations of the mean
