The answer is 2. If you multiply the brackets out then you will get -40 over -20, and a negative divided by a negative is a positive therefore it is 2.
Suppose the equation went like this
-12 -24= x
You would essentially just add them together and put a negative sign in front of it so the answer would be -36. But once you start dealing with parentheses and brackets it get more complicated than that. Comment if you have any more questions :)
Answer:
B is correct
Step-by-step explanation:
<u>Key skills needed: Functions, Identifying Functions</u>
1) A function has to have y = something
2) The only that has this is B
3) Therefore B is the answer.
<em>Hope you understood and have a nice day!! :D</em>
I think the answer is -4 if you subsitute x for 3
