Alexandra's family took a road trip to the Grand Canyon. Alexandra slept for the last 48 miles of the trip. If the total length of the trip was 800 miles, what percentage of the total trip had they travelled when Alexandra fell asleep?

They had travelled 6% of the total trip when Alexandra fell asleep.

Step-by-step explanation:

Given: Length of Total trip = 800 miles

Alexandra slept for the last 48 miles of the trip.

The percentage of the total trip had they travelled when Alexandra fell asleep

=

Hence, They had travelled 6% of the total trip when Alexandra fell asleep.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
