3 0

Answer:

(x + 4)

Step-by-step explanation:

\frac{ {x}^{2}  + 6x + 8}{x + 2}  \\  \frac{ {x}^{2}  + 4x + 2x + 8}{x + 2}  \\  \frac{ x(x + 4) + 2(x + 4) }{(x + 2)}  \\  \frac{(x + 2)(x + 4)}{(x + 2)}  \\  = ( x+ 4)

Hope this helps you.

Solve the system by graphing.
igor_vitrenko [27]

Answer:

Hi There the correct answer is {x,y} = {-1,-10}  

 

System of Linear Equations entered :

  [1]    3x - y = 7

  [2]    4x - 2y = 16

Graphic Representation of the Equations :

   y + 3x = 7        -2y + 4x = 16  

 

 

Solve by Substitution :

// Solve equation [1] for the variable  y  

 

 [1]    y = 3x - 7

// Plug this in for variable  y  in equation [2]

  [2]    4x - 2•(3x-7) = 16

  [2]    -2x = 2

// Solve equation [2] for the variable  x  

  [2]    2x = - 2  

  [2]    x = - 1  

// By now we know this much :

   x = -1

   y = 3x-7

// Use the  x  value to solve for  y  

   y = 3(-1)-7 = -10  

Solution :

{x,y} = {-1,-10}  

Hope it helps!

Arnold can read 3 pages in 7 minutes. Brenda can read 8 pages in 14 minutes. Who is the faster reader? Justify your answer.
Mrac [35]

Answer:

Brenda

Step-by-step explanation:

You can divide the number of pages by the number of minutes to find the amount of minutes it takes to read 1 page. For Arnold, 3 pages / 7 minutes = 1 page per approximately 0.43 minutes. For Brenda, 8 pages / 14 minutes = 1 page per approximately 0.57 minutes. Brenda reads slightly faster since 0.57 > 0.43

Write an equation that is parallel to y=-5/2x-5
NeX [460]

       A parallel equation (when graphed) will have the same slope, but a different y-intercept.

       As long as you keep y = -\frac{5}{2}x + b, you can input anything for b to solve this question.

       Given:

y = -\frac{5}{2}x - 5

       Equation of a parallel line:

y = -\frac{5}{2}x + 6, y = -\frac{5}{2}x + 1,356, y = -\frac{5}{2}x - 8, etc

     Example answer you can use:

             y = -\frac{5}{2}x - 8
