Rory is staying in a cabin on a hill 300 feet above sea level. she walks down the hill to the water’s edge. the equation of her average change in elevation over time is e = 300 – 10t, where t is the time in minutes since she left the cabin, and e is her elevation with regard to sea level. which values are viable points, and what are their values in the table relating t and e?

Answer with explanation:

If we draw a Vertical number line, Where Sea level Represents=0,

Point on number line where Rory is standing = +300 feet

Equation of average change in elevation over time is given by equation:

    e = 300 - 10 t

So, when t=0, e=300

and, when e=0 , gives ,

10 t= 300

→→Dividing both sides by 10

  t =30

→Average change

→Rate of change

Viable points →

e (feet)              300          0

t (minutes)          0            30

Which values are viable points, and what are their values in the table relating t and e?

a = not viable

b = 265

c = 0

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
