a mountain decends a mountain for 5 hours. On average, she climbs down 500 feet each hour. what is her change in elevation after
5 hours?
2 answers:
Answer: -2500 feet or 2500 feet down.
Step-by-step explanation:
Given : A mountain descends a mountain for 5 hours.
On average, she climbs down 500 feet each hour.
Since , we use negative sign to represent down or descend in quantity in integers.
Thus IN INEGERS, on average, she climbs -500 feet each hour.
Now, her change in elevation after 5 hours will be :-
Hence, her change in elevation after 5 hours= -2500 feet.

To find graph this, you need to understand the equation.
The formula is y=mx+b, m being slope and b being y-intercept.
We start out graphing by finding where the y-intercept is--and we see that our intercept is 2. Place a point on (0, 2).
Now, we need to add our slope. Start at (0, 2) and go up 4 units. Next go to the LEFT (we have a negative slope, remember?). Continue this pattern.
It should look like this once it's done:
The <span>Pythagorean Theorem tells us that 
where c is the </span><span>hypotenuse and a and b are the other two sides. To solve for one of the shorter sides we need to rearrange:
We can then substitute known values, and solve:
