m : n = 2 : 1
( x, y ) = ( (1*3 + 2*(-2))/(2+1) ; (1 * (-1) + 2 * 3) /(2 + 1) ) =
= ( (3-4)/3 ; (-1+6)/3 ) 1.67
Answer:
Jose's solution is not correct, the auditorium has
rows
Step-by-step explanation:
we have

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


Using a graphing calculator
The values of x are

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