The degree of a vertex is <br><br> Help please

Nina [5.8K]

Answer:

is the number of graph edges which touch v

Step-by-step explanation:

To find the degree of a graph, figure out all of the vertex degrees. The degree of the graph will be its largest vertex degree. The degree of the network is 5.

Once you know the degree of the verticies we can tell if the graph is a traversable by lookin at odd and even vertecies. First lets look how you tell if a vertex is even or odd.

Select the two values of x that are roots of this equation.<br> X2 + 2x - 5 = 0

LenaWriter [7]

Answer:

$x=-1+\sqrt{6 }$

$x=-1-\sqrt{6 }$

Step-by-step explanation:

$x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

Ignore the A before the ±. It wouldn't let me type it correctly.

x² + 2x - 5 = 0

a = 1

b = 2

c = - 5

$x=\frac{-2±\sqrt{2^{2}-4((1)(-5)) } }{2(1)}$

$x=\frac{-2±\sqrt{4-4((1)(-5)) } }{2(1)}$

$x=\frac{-2±\sqrt{4+20 } }{2(1)}$

$x=\frac{-2±\sqrt{24 } }{2}$

$x=\frac{-2±\sqrt{(2)(12) } }{2}$

$x=\frac{-2±\sqrt{(2)(2)(6) } }{2}$

$x=\frac{-2±\sqrt{(2)(2)(2)(3) } }{2}$

$x=\frac{-2±(\sqrt{2} )(\sqrt{2})(\sqrt{(2)(3) )} }{2}$

$x=\frac{-2±2\sqrt{6 } }{2}$

Two separate equations

$x=\frac{-2+2\sqrt{6 } }{2}$

$x=\frac{-2-2\sqrt{6 } }{2}$

$x=-1+\sqrt{6 }$

$x=-1-\sqrt{6 }$

Factor x2 – 8x + 15. Which pair of numbers has a product of ac and a sum of b?_______ What is the factored form of the trinomial

NeX [460]

Answer:

-3, -5 ;;; (x-5)(x-3)

Step-by-step explanation:

The current equation we have is x² - 8x + 15

Now, we will have to filter the middle term is such a way that the there would be a common factor for the 2 groups out of the 4.

ok, so how do we divide the middle term?

Simple, we multiply the consonant in the equation with the numerical consonant of the first term...

The consonant we have : 15

numerical consonant: 1

The product would be 15 × 1 which is 15.

Now, we will have to break -8x in a way by which the two terms product would be 15.

The only possible way is -3 and -5

The equation now would be = x² - 3x - 5x + 15

Now, we will need to break these 4 terms to 2.

x ( x - 3 ) -5 ( x - 3 )

( x - 5 )( x - 3 )

Now, we got the factored form and the two numbers we have used are-3 and -5.

Hope I helped!
