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

x^2+1/2x+1/16=4/9 Factor the perfect-square trinomial on the left side of the equation. (x + )² = 4/9
Nezavi [6.7K]
The missing number is the square-root of the constant term on the left-hand-side, which equals sqrt(1/16)=1/sqrt(16)=1/4.
Check:
(x+1/4)^2=x^2+2*(1/4)x+(1/4)^2=x^2+x/2+1/16.   ok

Answer: x= 1/4
