N is -4
$6n + 9 = - 3n - 21 - 6 \\ 9n = - 36 \\ n = \frac{ - 36}{9} = - 4$

good luck

Answer:

n=-4

Step-by-step explanation:

6n + 9 = -3n - 21 - 6

Add 3n to each side

6n+3n + 9 = -3n+3n - 21 - 6

9n+9 = -27

Subtract 9 from each side

9n+9-9 = -27-9

9n = -36

Divide each side by 9

9n/9 = -36/9

n = -4

Solve for possible values of x. 3x^2 = 18x

uysha [10]

(0,0) and (6,0)

First we subtract 18x from both sides

3x²-18x=0

Factor out a 3x

3x(x-6)=0

This means that x is either 0 or 6

What is the equation of the line of the best fit for the following data? Round to the slope and y-intercept of the line to three

BigorU [14]

Answer:

D. $y=-0.927x+13.634$

Step-by-step explanation:

We graph the points on the graph. The graph is attached.

Let us take two points (1, 14) and (15, 1), and calculate the slope $m$ between them <em>(we choose these points because the line passing through them will be the best fit for all points) </em>

$m=\frac{14-1}{1-15} =\frac{13}{-14} =-0.9286$

Thus we have the equation

$y=-0.9286x+b$

Let us now calculate $b$ from the point $(1,14)$

$14=-0.9286(1)+b$

$b=14.9286$

So the equation we get is

$y=-0.9286x+14.9286$

Let us now turn to the choices given and see which choice is closest to our equation: we see that choice D. $y=-0.927x+13.634$ is the closest one, so we pick it.
