The gas mileage m, in miles per gallon, obtained during a long trip is given by m equals negative 1 half vertical line s minus 55 vertical line plus 25 where s is the speed of Kate's automobile in miles per hour and 40 less or equal than space s less or equal than 70. At what constant speed can Kate drive to obtain a gas mileage of exactly 22 miles per gallon?

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
