Answer:
x+2=x+2
Step-by-step explanation:
Combine like terms
3x+(-2x) and (-7)+9
x+2=x+2
Y= 17 would be the answer.
For something to be a function, it needs an input (x) and an output (y).
There is no x is this answer.
I hope this helps!

Answer: Hello!
Let's start with the word TRISKAIDEKAPHOBIA wich has 17 letters (some of them repeat, but it does not matter in this problem)
We want to know how many permutations we can do with 17 letters: then think this way, Lets compose a word. The first letter of this word has 17 options, the second letter of the word has 16 options (you already took one of the set) the third letter of the word has 15 options, and so on.
The total number of permutations is the product of the number of options that you have for each letter, this is:
17*16*15*14*....*3*2*1 = 17! = 3.6e+14
(b) FLOCCINAUCINIHILIPILIFICATION now we have 30 letters in total, using the same reasoning as before, here we have 30! permutations; this is
30! = 2.65e+32
(c) PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS: now there are 47 letters.
then P = 47! = 2.59e+59
(d) DERMATOGLYPHICS: here are 18 letters, then:
p = 18! = 6.4e+15
22 feet. Using the sine rule theory: 20/sin(65)=x/sin(90). You know that it's 90 degrees because you assume the ground and the building make a 90 degree angle. So, you cross multiply and get 20sin(90)/xsin(65) and solve for x.
The inverse of the given function is y = (12-x)/6
<h3>Inverse of a function</h3>
Given the following function expressed as:
f(x) = -6x +1/2
Replace y with x
x = -6y + 1/2
Make y the subject of the formula
6y = -x + 12
y = (12-x)/6
Hence the inverse of the given function is y = (12-x)/6
