Here are some more questions I'm having trouble with. Please walk me through them so I can fully understand them. #2: Let A be (5,9), B be (-3,-5), and C be (1,1). The median of a triangle connects a vertex of a triangle to the midpoint of the opposite side. *Another note:...

Thanks for replying so fast! Once you got to "subtract the second equation," I got a little confused. So basically its, 100-81=A(100-63), like you said. Does the B stay put? And what do you mean by "solve for A" and "put A into either equation?" T...

I really need help with my math homework today, because I am totally confused! Please give me the answer, but also walk me through it, too, so I can fully understand it, because just the answer won't really help. #1: A math teacher wants to curve a set of grades. *Just a n...

Another question: A cell phone company charges \$60 for a cell phone and \$40 per month under its economy plan. Formulate and graph a model that can be used to determine the total cost, C(t), of operating a cell phone for t months. Find the total cost for 5 and 1/2 months of ser...
