You reflect triangle PQR, with vertices P(-2, -4), Q(-3, -1), and R(-4, -4), across the y-axis to get triangle P′Q′R′. What are the coordinates of triangle P′Q′R′? A. P′(-2, 4), Q′(-3, 1), R′(-4, 4) B. P′(2, -4), Q′(3, -1), R′(4, 4) C. P′(-2, 4), Q′(-3, 1), R′(4, -4) D. P′(2, -4), Q′(3, -1), R′(4, -4)

David and alton are training for a race. they spend 35 minutes stretching and then go on a 5 mile practice run. david runs at a pace of 7 min/mile. alton runs at a pace of 8 min/mile. write an equation for each runner that shows the total length of their workout. then solve each equation showing your work
