<u>Cos C</u> : adjacent side of ∠C / hypotenuse
Answer:
Part A: So the solution for 4 = 2x-1 is -2. Why they're intersecting is because <em>x</em> is -0.5 in both cases. 2/4, as we already know, is 0.5. Since, this -2/4, we can just make 0.5 negative, so -0.5. -0.5 times 4 = -2, so x is -0.5. For y = 2x-1, multiply -0.5 by 2, which would get you -1. Then after that subtract 1, for -2.
Part B:
Well, notice how none of the entries for y = 4x and y = 2x-1 match. That would mean the answer wouldn't be an integer. (Attachment is the table)
Part C:
First, graph both y = 4x and y = 2x-1. After that, find where the two equations' y-coordinates are the same (So, on a graph, where they intersect.). The y-coordinate in common is your answer.
5x+15 because you have to do 5 times x which is 5x then 5 times 3 which is 15.
