Arly is traveling to visit family. She drives x miles on the first day and y miles on the second day for a total of 800 miles. What are the domain and range of this relationship?

domain: 0 ≤ x ≤ 800
range: 0 ≤ y ≤ 800

domain: 0 ≤ x ≤ 400
range: 0 ≤ y ≤ 400

domain: x ≥ 0
range: y ≥ 0

domain: x ≤ 800
range: y ≤ 800

thats not a system of equations, that is a solution

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

answer: c.  

step-by-step explanation:
