Which two expressions are equivalent?

not sure but i think its the thrid one

Step-by-step explanation:

option 3

Step-by-step explanation:

12 - (y*2) = 12 - (2*y)    Commutative property

2*y = y*2

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)

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
