Abicyclist rides down a hill and her speed is increasing. then she rides up a hill and her speed is decreasing. she stops to rest for a while on top of this hill. which graph could represent her velocity for this whole period of time?

The graph that goes up and then down and stays at the bottom of the graph

Step-by-step explanation:

this is because her velocity would increase when she goes down the hill and would go down when she is going up the hill, when she rests she wouldn't have any velocity thus it being at the bottom of the graph.

I just had this question and there was no answer on this site so i thought i should add one. when it didn't have an answer i actually read the problem and realized i knew the answer lol.

Hope this helps!

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
