An electronics store sells an average of 117 home theater systems per month at a price of $213 each. When the store drops its price to $192, it sells 28 home theater systems more each month. At what price should the store sell the home theater systems to maximize its revenue?

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cxd)(x)

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie
