5.) Students are on a 248.5-kilometer bike trip. They rode 52.4 kilometers on the first day. They rode 0.4 of the remaining distance on the second
day. How many kilometers do they have left to ride? *

given that    bisects ∠dbc, which statement must be true? the answer is:   m∠abd = m∠abc 

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
