Answer:

Step-by-step explanation:
Given: 
If there is a coefficient in front of a
or
, that means it becomes an exponent.

Simplify the exponent.

When there is addition between two logarithms or natural logarithms, it means they multiply together.

No, because there are TWO values of y for a certain value of x
say x=5, then y=2 and y=-2
That does not satisfy the concept of the function.
3x-5y=-15 What you do to one side, you must do to the other.
-<u>3x -3x
</u><u />-5y=-3x-15
<u>-5y</u>=<u>-3x</u> <u>- 15</u>
-5 -5 -5
Final Answer: y=3/5x + 3
3^-4 = 1/3^4 = 1/81
hope it helps!
