10 out of every 65 students order pizza for lunch. There are 416 students at her school. How many students will eat pizza at her

Studentka2010 [4]

Answer:

Step-by-step explanation:

First, you divide 416 by 65. This gets you 6.4. But it's not 1 in 65 eating pizza, it's 10 out of 65, so then you multiply 6.4 by 10, getting 64.

$f(x)=2x^2-4x+1$

Substitute the values of x to the equation of the function f:

$x=-1\to f(-1)=2(-1)^2-4(-1)+1=2(1)+4+1=7\\\\x=2\to f(2)=2(2^2)-4(2)+1=2(4)-8+1=1$

Therefore we have two points (-1, 7) and (2, 1).

We can calculate the slope of line l.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute:

$m=\dfrac{1-7}{2-(-1)}=\dfrac{-6}{3}=-2$

<h3>Answer: A) -2.</h3>
