Write the inverse variation equation of the following. Y varies inversely with x and y = 9 when x= 14. Choose one answer. xy=126 xy=14/9 xy=42 Assume the y varies inversely with x and y = -3 when x = 4. Write the indirect variation equation for the relationship. Choose one answer. xy=-3/4 xy=4/-3 xy=-12 We are given an inverse variation equation of xy= 10. Complete the statement, y as x increases. Choose one answer. Increases decreases remains constant Assume that y varies inversely with x. If y = 7 when x = -3, find y when x = 7. Choose one answer. y=-7/3 V=-3 y=-21 Assume that y varies inversely with x. If y = 8.8 when x = 2.4, find x when y = 2.1. Round to the nearest tenth. Choose one answer. x=8.5 x=1.6 x= 10.1 Assume that y varies inversely as x. If y = -6 when x= -2, find y when x= 5. Choose one answer. y= 1.7 y=2.4 y=3 Assume that y varies inversely as x. lf y = -6 when x =-2, find y when x= 5. Choose one answer. y= 1.7 y=2.4 y=3 Use the Law of the Lever to solve the following. Mark sits 4.5 feet from the center of the seesaw to balance a friend who weighs 53 lbs and is sitting 6 feet from the center. How many pounds does Mark weigh? Round to the nearest hundredth. Choose one answer. 39.75 lb 70.67 lb 55.78 lb Use the Law of Levers to solve the problem. The number of chairs on a ski lift varies inversely as the distance between them. A ski lift can handle 32 chairs when they are 30 feet apart. If 40 chairs were used, how many feet should be left between each pair? Choose one answer. 24 ft 37.5 ft 32 ft Use the Law of Levers to solve the following. A rectangle has a width of 22 inches and a length of 18 inches. Find the length of another rectangle of equal area, if the width is 20 inches. Choose one answer. 16.4 in 17.6 in 19.8 in
