What are the x-intercepts of the graph of f(x) = (2x-1)(2x-5)? Show your work.
nlexa [21]

Answer:

Step-by-step explanation:

The x intercepts are obtained by equating the factors to zero.

2x - 1 = 0

2x = 1

x = 1/2

2x - 5 = 0

2x = 5

x = 5/2

x = 2 1/2 or 2.5

The graph of f(x) = (2x -1)*(2x - 5) is given below. The x intercepts are labeled.

Find the midpoint of the segment with the following endpoints.<br> (7, -2) (1, -10)
dem82 [27]

Answer:

<h2>(4, -6)</h2>

Step-by-step explanation:

The formula of a midpoint of the segment AB:

M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)

We have A(7, -2) and B(1, -10). Substitute:

M_{AB}\left(\dfrac{7+1}{2};\ \dfrac{-2+(-10)}{2}\right)\\\\M_{AB}\left(\dfrac{8}{2};\ \dfrac{-12}{2}\right)\\\\M_{AB}(4;\ -6)

What is the denominator of the simplified expression? (startfraction 2 n over 6 n + 4 endfraction) (startfraction 3 n + 2 over 3
max2010maxim [7]

n/3n - 2.

The denominator of the given simplified expression is

The given expression is ( 2n/6n + 4 ) ( 3n + 2/ 3n - 2 )

To find the denominator of the simplified expression :

First, simplify the given expression as below ;

( 2n/6n + 4 ) ( 3n + 2/ 3n - 2 )

( 2n/2₍₃ₙ ₊ ₂₎ ( 3n + 2/ 3n - 2 )  ( here by taking the common term 2 outside the factor )

= (n/1) ( 1/ 3n - 2 ) ( here by simplifying the factors )

= n/3n - 2.

Therefore, ( 2n/6n + 4 ) ( 3n + 2/ 3n - 2 ) = n/3n - 2

Therefore the result of the given simplified expression is = n/3n - 2.
