Write a direct variation equation that relates x and y. Find the value of k. y = kx Direct variation equation 30 = k(5) Replace y with 30 and x with 5. 6=k Divide each side by 5. Therefore, the equation is y = 6x. b. Use the direct variation equation to find x when y = 18. y 6x Direct variation equation 18 6x Replace y with 18. 3 =x Divide each side by 6. Therefore, x = 3 when y = 18. Try this problem:Suppose y varies directly as x. Write a direct variation equation that relates x to y. Then sol 4. If y = 4 when x = 2, find y when x = 16. DVD acer

A sprinter enters the 60 m mark of the race with a velocity of 12.0 m.s-1. He continued to accelerate at a rate of 0.5 m.s-2 over the next 10 m covering this in 0.90s. Calculate the velocity of the sprinter when he reached 70 m
