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

Find the value of x for which m is parallel to n A) 10 B) 12 C) 40 D) 52

Klio2033 [76]

Answer: $x=5\textdegree$

Explanation:

Since we have given that

line m and line n are parallel to each other,

So,

Corresponding angles are equal , as shown in the figure ,

According to question,

$19x\textdegree=180\textdegree-17x\textdegree\\\\19x\textdegree+17x\textdegree=180\\\\36x\textdegree=180\textdegree\\\\x=\frac{180}{36}\\\\x=5\textdegree$

Hence, $x=5\textdegree$
