A chemist has 500 ml of a 30% acid solution. She adds x milliliters of a 10% acid solution. Which statement is true about the graph of the function that represents the concentration of the final solution? The horizontal asymptote y = 30 means that the final concentration will always be less than 30%. The horizontal asymptote y = 10 means that the final concentration will always be greater than 10%. The vertical asymptote x = 500 means that the volume of solution will always be greater than 500 ml. The vertical asymptote x = 0 means that the volume of the solution will always be greater than 0.
