Answer:
15.71
Step-by-step explanation:
Answer:
The x -coordinate(s) of the point(s) of intersection of these two polynomials are 
The sum of these x -coordinates is 
Step-by-step explanation:
The intersections of the two polynomials, p(x) and q(x), are the roots of the equation p(x) = q(x).
Thus,
and we solve for x

Using Zero Factor Theorem: = 0 if and only if = 0 or = 0


The solutions are:

The sum of these x -coordinates is

We can check our work with the graph of the two polynomials.
Given:
maximum seating 76,867 fans
cost of tickets $161
revenue: f(x) = 161x
y = 161x
domain is the x values
range is the y values
using the formula: y = 161x where x = 76,867
y = 161(76,867)
y = 12,375,587
domain is 76,867
range is 12,375,587
Answer:
Just substitute "x" with "3".
Step-by-step explanation:
y = 2.4x + 3.1
y = 2.4(3) +3.1
y = 7.2 + 3.1
y= 10.3
