Question:

Negative 2 left parenthesis 4 x minus 3 right parenthesis minus 4 x equals 126
What is the value of x

Answers

22 - 4x = 12x + 126
     +4x  = +4x

22    = 16x + 126
-126 =        - 126

-104 = 16x
/16       /16

-6.5 = x

[tex]22-4x=12x+126\ \ \ \ |Subtract\ 12x\\\\
22-16x=126\ \ \ |Subtract\ 22\\\\
-16x=104\ \ \ |Divide\ by\ -16\\\\
x=-6,5\\\\Solution\ is\ x=-6,5.[/tex]

The coefficient  is  [tex]r =0.81[/tex]

Step-by-step explanation:

From the question we are told that

      [tex]cov(x, y )= 1260[/tex]

      [tex]s_x^2 = 1600[/tex]

     [tex]s_y^2 = 1225[/tex]

Generally the coefficient of determination is mathematically represented as

      [tex]r = [ \frac{cov(x,y)}{ \sqrt{s_x^2} * \sqrt{s_y^2} } ]^2[/tex]

substituting values

      [tex]r = [ \frac{ 1260}{ \sqrt{1600} * \sqrt{1225} } ]^2[/tex]

     [tex]r =0.81[/tex]


[tex]If c o v (x comma space y )space equals space 1260, s subscript x squared equals 1600, and s subscri[/tex]

Hey there!

To figure out what "x" means, you can divide the numbers 126 and 14  . . .

126 divided by 14 = 9

9 x 14 = 126

9 = x


x = 9


Hope this helps you.
Have a great day!

The most easiest step that we could so here is to first simplify them. We would simplify the term by its result.

(126)÷14=9.

By dividing these both, we would the new able to solve what would (x) be.

Therefore, x= 9.

14 x's 9 = 126
