You take 6 steps forward and 8 steps backwards how many steps have you taken?

It’s a subtracting integer question.

So would it be 6-(-8)?

I think it would be simply 6-8

Step-by-step explanation:

becuase 6-(-8) is really 6+8, which isn't correct. It could also be 6-(8), but I'm not sure.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

the answer is  

a.
