One month, a music site observed that 60% of the people who downloaded songs from its site downloaded q sam's latest single. the equation below represents this information, where x represents the total number of people who ddownloaded songs from the site that month: x = 0.6x + 384 how many people who downloaded songs from the site that month downloaded q sam's latest single?

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

Which of the following circles have their centers on the x-axis? check all that apply.
