Alfred is taking a trip. he drove 150 mi and then stopped to refuel. he will drive 60 mph to finish his trip. let x represent the hours it takes for alfred to complete the rest of his trip, and let y represent the total distance traveled.

complete the function equation that relates alfred’s total distance traveled to his time.

y=+

The total distance traveled by Alfred is the sum of the distance he traveled before and after refueling.

The distance he traveled before refueling is 150 miles. After refueling, the distance he traveled is the product of his speed and time, x hours. Therefore, his total distance traveled is,
 
                                y = 60x + 150

One unique triangle, because those angles add up to 180, and that's how many degrees there are in one triangle.
