(90) points ill give immideatly but gotta be right Maria and her parents are hiking in the mountains. During one hike, Maria monitored their changing elevation and displayed it in the graph below. Which of the following BEST describes a functional relationship shown in the graph? A Maria's elevation remained constant for two hours. B Maria's elevation decreased between 1:00 and 3:00. C Maria's elevation increased between 9:00 and 12:00. D Maria spent more time decreasing her elevation than increasing her elevation.

(C) Maria's elevation increased between 9:00 and 12:00

Step-by-step explanation:

Looking at the graph, we can test each statement.

For A, it says Maria's elevation remained constant for 2 hours. Looking at the graph, we can see that it remained constant for just one hour, so this is eliminated.

For B, Maria's elevation decreased between 1:00 and 3:00, we can see that while x is between 1:00 and 3:00, the y is decreasing, meaning this statement is false - this is eliminated.

For C, Maria's elevation increased between 9:00 and 12:00, we can see that while x is between 9:00 and 12:00, the graph is increasing - which means this is correct.

For D, Maria spent more time decreasing her elevation than increasing, we can count how many hours were spent doing each. Comparing the x-axis, we can see that Maria spent 5 hours increasing and 3 hours decreasing, meaning that Maria spent more time INCREASING than decreasing, making this statement false.

Hope this helped!

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
