A total of 35 students are going on the field trip. There will be 5 more girls than boys. Which system of equations represents this? B + G = 35 & B = G + 5 B + G = 35 B + G = 35 & G = B - 5 G - B = 35 & G = B + 5 & G = B + 5 Which linear equation represents this? X y = ½x + 14 y = ½x + 12 y = 2x + 12 y = 2x - 4 Y 14 4 8 16 18 12 20 16 Freddy threw a ball in the air that followed the equation h = -16t2 + 48t + 6 where h=height of ball, and t=time(seconds). When did the ball land on the ground? between 3 & 4 seconds between 2 & 3 seconds between 1 & 2 seconds before 1 second Freddy threw a ball in the air that followed the path h = -16t2 + 48t + 6 where h=height (feet) & t = time (seconds) What was the maximum height of the ball? 40 feet 50 feet 38 feet 42 feet Which exponential function represents Ted's bank balance when earning 4% interest per year?
