Let A = {2, 3, 5} and B = {x, y}. Let p1 and p2 be the projections of A ✕ B onto the first and second coordinates. That is, for each pair (a, b) A ✕ B, p1(a, b) = a and p2(a, b) = b. (a) Find p1(2, y) and p1(5, x). p1(2, y) = p1(5, x) = What is the range of p1? (Enter your answer in set-roster notation.) (b) Find p2(2, y) and p2(5, x). p2(2, y) = p2(5, x) = What is the range of p2? (Enter your answer in set-roster notation.)

Find the value of the variable and the length of each secant segment.

Suppose you are an avid reader and are looking to save money on the cost of books instead of paying about $20 for each book, you decide to look into purchasing a kindle for $120 you can purchase e-books for about $5 each 1. find the slope-intercept equation for the cost of the hard copy of books using x to represent the number of books 2. find the slope-intercept equation for the cost of the kindle with cost of e-books using x to represent the number of books

Determine if the equation defines y as a function of x: 2xy = 1. yes o no
