Since you didn’t specify that it needed to be y as a function of x, all of the above equalities can be rewritten as functions. However, in case that you meant to imply that, A and B are both not valid for y as a simple function of x.

When you divide a number by 1/2, the result is

Nikitich [7]

Let us analyze the following situation: The number we want to divide by 1/2 is X. We can write:
X/(1/2)=(X/1)/(1/2)=(X*2)/(1*1)= X*2,
which means that the number that is divided with 1/2 is multiplied by 2 (twice the original number).

Answer:

12^x

Step-by-step explanation:

Absolute. Value. Of. |12^x-8|. Is. 12^x + 8

12^x + 8= 2^3. So. 12^x. +8.=8

12^x+8-8=8-8

12^x=0. Left. With. 12^x?
