Mathematics
1 answer:
SOVA2 [1]3 years ago
3 0

Answer:

Firstly

f(x)=3x-2=y then

Interchanging x and y we get

x=3y-2

x+2=3y

y=(x+2)/3

f-1(x)=(x+2)/3

f-1(13)=(13+2)/3

f-1(13)=5

What ordered pair is a solution for y-4=7(x-6)
777dan777 [17]

The ordered pair (6 , 4) is a solution for y - 4 = 7(x - 6)

Step-by-step explanation:

The point-slope form of a linear equation is:

y-y_{1}=m(x-x_{1}) , where

  • m is the slope of the line
  • (x_{1},y_{1}) is a point on the line

Any point on the line is a solution for the equation of the line

The solution of an equation is the values of x and y which make the left hand side is equal to the right hand side

∵ The equation is y - 4 = 7(x - 6)

- Compare the equation by the point-slope form above

∴ m = 7

∴ x_{1} = 6 and y_{1} = 4

- That means point (6 , 6) lies on the line

∴ Point (6 , 4) is a point on the line which represents the

   given equation

∵ Any point on a line is a solution of the equation of that line

∴ (6 , 4) is a solution of the equation

The ordered pair (6 , 4) is a solution for y - 4 = 7(x - 6)

g True or False: Regression analysis is used for prediction, while correlation analysis is used to measure the strength of the a
larisa [96]

Answer:

The given statement is true.

Step-by-step explanation:

Regression Analysis:

  • Regression analysis is a technique that help us to find or define a relationship between a dependent and an independent variable.
  • It helps us to predict the dependent variables with the help of independent variables.
  • Various techniques are used for the prediction of independent variable.
  • It is a type of predictive statistical technique and helps us to find whether there is a significant relationship between the dependent and the independent variable.

Correlation analysis:

  • Correlation is a technique that help us to find or define a relationship between two variables.
  • It is a measure of linear relationship between two quantities.
  • It is not necessary that the that out of the two variable one needs to be dependent and the other to be independent.
  • Correlation can be positive, negative or zero correlation.

Thus, the given statement is true.
