Practice, practice, practice. And ask questions.
Use this property of logarithms:

Your equation transforms into:

Now, you have to apply the definition of a logarithm to express the equation in exponential form:

In case you don't remember, this is the definition of a logarithm:

The log is the exponent (y) you have to raise the base (b) to in order to get the power (x).
Finally, solve the rational equation:



The correct answer is d.
30 degrees is what the answer is because it says it in the question
Answer:
They both have the #5 and they both have 3 #'s that are prime?
Step-by-step explanation:
Y= 1/4x+b
-3= 1/4(-4) +b
-3= -1 +b
-2 = b
y=1/4x-2
