Untconstant rate. The table below shows the number of tickets sold (S) as a function of time (t). S (show tickets) 550 280 100
t (time, in hours,
since 10AM)
Write an equation expressing S as a funtion on t.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the answer is  

a.

28 ft2

step-by-step explanation:

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
