<h3>Answer:</h3>

n = -17.

<h3>Step By Step Explanations:</h3>

1) Divide both sides by -9.

n + 6 =  -  \frac{99}{9}

2) Simplify 99/9 to 11.

n + 6 =  - 11

3) Subtract 6 from both sides.

n =  - 11 - 6

4) Simplify -11 - 6 to -17.

n =  - 17

Therefor, the answer is n = -17

Which is the equation of the parabola with focus (6, 2) and vertex (6, –4)?
SVETLANKA909090 [29]

Based on the calculations, the equation of this parabola is equal to (x - 6)² = 16(y + 4).

<h3>How to determine the equation of this parabola?</h3>

Mathematically, the standard equation with the vertex for a parabola is given by:

(y - k)² = 4a(x - h) for horizontal parabola.

(x - h)² = 4a(y - k) for vertical parabola.

<u>where:</u>

  • h and k are the vertex.
  • a is a point.

By critically observing the points, we can deduce that both the focus and vertex lie on the same vertical line x = 6.

<u>Given the following data:</u>

Focus with points = (6, 2).

Vertex (h, k) = (6, –4).

<u>Note:</u> a = 2 - (-4) = 2 + 4 = 6.

Substituting the given parameters into the formula, we have;

(x - 6)² = 4 × 4(y - (-4))

(x - 6)² = 16(y + 4).

Graph y = 4x-9 please
stiks02 [169]

Answer:

(0, -9) (1, -5)

Step-by-step explanation:

We know from the equation y = 4x -9, that the slope of the line is 4, and the point that the line crosses the y-intercept is at -9. So, your first point would be at (0, -9) and if you go one value over on the x-coordinate, that means the y-coordinate will go 4 up. So your final point will be (1, -5). The point could also be (2, -1), (3, 3), (4, 7), (5, 11), etc.

I Hope That This Helps! :)
