1. The total number of seats in an auditorium is modeled by f(x) = 2x2 – 6x, where x represents the number of rows. How many row

irakobra [83]

Answer:

Jose's solution is not correct, the auditorium has $16$ rows

Step-by-step explanation:

we have

$f(x)=2x^{2} -6x$

where

f(x)------> is the total number of seats in an auditorium

x----> represents the number of rows

How many rows are there in the auditorium if it has a total of 416 seats?

Find the value of x for f(x)=416 seats

substitute the value of f(x) in the equation

$416=2x^{2} -6x$

$2x^{2} -6x-416=0$

Using a graphing calculator

The values of x are $x=-13, x=16$

The solution is

x=16 rows because the number of rows can not be a negative number
