Triangle A B C is shown. Lines are drawn from each point to the opposite side and intersect at point D. They form line segments

A G, B E, and C F.
In the diagram, which must be true for point D to be an orthocenter?

BE, CF, and AG are angle bisectors.
BE ⊥ AC, AG ⊥ BC, and CF ⊥ AB.
BE bisects AC, CF bisects AB, and AG bisects BC.
BE is a perpendicular bisector of AC, CF is a perpendicular bisector of AB, and AG is a perpendicular bisector of BC.

Which is the graph of the function f f(x)=(x-4)(x+4)?
ozzi

Answer:

4th bubble

Step-by-step explanation:

First FOIL: <em>f</em>(x) = x² + 3x - 4. Then convert from <em>Standard</em><em> </em><em>Form</em><em> </em>[y = Ax² + Bx + C] to <em>Vertex</em><em> </em><em>Form</em><em> </em>[y = A(X - H)² + K], where (<em>h</em><em>,</em><em> </em><em>k</em>) is the vertex and -h gives the OPPOSITE terms of what they really are. So, you do this by completing the square [½B]²:

  1. 2¼ = [½(3)]² [then figure out figure out how much you need to get to -4 (k)]
  2. 2¼ - 6¼ = -4
  3. Your vertex formula is <em>y</em><em> </em><em>=</em><em> </em><em>(</em><em>x</em><em> </em><em>+</em><em> </em><em>1</em><em>½</em><em>)</em><em>²</em><em> </em><em>-</em><em> </em><em>6</em><em>¼</em><em>.</em>

Remember, -h gives the OPPOSITE terms of what they really are, so your vertex is (-1½, -6¼).

Determine which of the lines if any are parallel or perpendicular?
Tcecarenko [31]

Answer:

y=6x-2 is perpendicular to the 6y=-x+7

y=6x+1 is parallel to the y=6x-2

Step-by-step explanation:

if product of two lines gradient is -1 than lines are perpendicular

gr y=6x-2

    y=mx+c m=gradient

1)m=6

2)m=-1/6

3)m=6

if gradients of 2 lines are equal they are paralel
