If the mean of: 2x, x,(2x−11),(x−3) is equal 4, then the value of x is:

Step-by-step explanation:

Given data : 2x , x , 2x - 11 , x - 3

Mean = 4

N ( number of items ) = 4

Σx = 2x + x + 2x - 11 + x - 3

To find : value of x

Finding the value of x

We know that ,

Mean =

plug the values

Collect like terms

⇒

Apply cross product property

⇒

Move 14 to right hand side and change it's sign

⇒

Add the numbers

⇒

Divide both sides of the equation by 6

⇒

Calculate

Hope I helped!!

Best regards!!!

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: '
