X + 1/4x = 15
4/4x + 1/4x = 15
5/4x = 15
5x = 60
x = 12
Answer:

Step-by-step explanation:
We want to simplify:

We first simplify the numerator to obtain:

Next the quotient rule:

We apply this quotient rule to get:

Simplify exponents:

Therefore the given expresion simplifies to:

Answer:
A
Step-by-step explanation:
Answer:
For functions, the two notations mean the exact same thing, but "f (x)" gives you more flexibility and more information. You used to say "y = 2x + 3; solve for y when x = –1". Now you say "f (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one").
