Answer:
Juan wins the race
Step-by-step explanation:
<em>The complete question is attached.</em>
<em />
Time is on the horizontal axis.
Distance is on the vertical axis.
If you look first at y-axis (vertical), you will see that both lines (curves) go upto a distance of 4 miles. So, the race is of 4 miles. Both of them finish.
Now,
If you look at the corresponding x-axis value of where each curve ends, you will see:
Antonio finishes at 15 mins
Juan finishes at 13 minutes
So we can successfully say that Juan wins the race since he finishes 2 mins faster than Antonio.
Juan wins the race
Answer:
(f + g)(x) = 2x
(f - g)(x) = 16
(fg)(x) = - 64
(f/g)(x) = (x + 8)/(x - 8) Domain: x < 8 ∪ x > 8
Step-by-step explanation:
(f + g)(x) = f(x) + g(x) = x + 8 + x - 8 = 2x
(f - g)(x) = f(x) - g(x) = x + 8 - (x - 8) = x + 8 - x + 8 = 16
(fg)(x) = f(x)g(x) = (x + 8)(x - 8) = - 64
(f/g)(x) = f(x)/g(x) = (x + 8)/(x - 8)
x - 8 ≠ 0
x ≠ 8
Domain: x < 8 ∪ x > 8
