The hawk is closer to the ground after 8 minutesIt is 130 feet closerHow to determine the valuesWe have the equation as;y = −20x+350. This represents the altitude y in feet of a hawky=−10x+400. This represents the altitude y in feet of the eagleAlso, x represents the descending time in minutesNow, let's substitute the value of x as 8 minutes in the equationsIf x = 8For equation (1)y = - 20(8) + 350expand the brackety = - 160 + 350y = 190 feetFor equation (2)y = -10(8) + 400expand the brackety = -80 + 400y = 320 feetThe hawk is closer after 8 minutesThe distance from the ground(eagle) - The distance from the ground(hawk)320 - 190130 feetHence, the hawk is closer to the ground Learn more about functions here:https://brainly.com/question/25638609#SPJ1
