Answer:

b.  x = 11/8, x = 59/72.

Step-by-step explanation:

4|8x - 6| = 5|-8x + 7|

square both sides:

16(64x^2 - 96x + 36) = 25( 64x^2 - 112x + 49)

1600x^2 - 1024x^2 - 2800x + 1536x + 1225 - 576 = 0

576x^2 - 1264x + 649 = 0

x = [1264 +/- √(1264^2 - 4 * 576* 649)] / (2*576)

x = 11/8, x = 59/72.

Answer:

Explained below.

Step-by-step explanation:

Consider the variables height and weight.

It is usually seen that taller people are heavier than shorter people.

So a regression analysis can be used to specify this belief.

The statistical questions that are being asked here are:

  • What the independent and dependent variables?
  • Are there any other factor influencing the dependent variable other than the independent variable?

The variable <em>Y</em> is considered as the dependent variable and the variable <em>Y</em> is considered as the independent variable.  And the main purpose of the regression analysis is to predict the value of <em>Y</em> when the value of <em>X</em> is given.

The linear regression model can be used to predict the past and future value of the dependent variables provided that the independent variables for those times are provided.

If f(x)=x sqrt -25 and g(x)=x-5, what is the domain of (f/g)(x)?
givi [52]

Answer:

<h2>R-{5}</h2>

Step-by-step explanation:

f(x)=x²-25=(x-5)(x+5)

g(x)=x-5

(f/g)(x)=<em>(x-5)</em>(x+5)/<em>(x-5)</em>=x+5;   for x≠5

D=R-{5}
