The simplified expression for the given function is 2x + 4 - ( 1 / x-1). The correct option is A.
<h3>What is an expression?</h3>
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the functions are f(x) = x + 2 and h(x) = 1 / x-1. The value of the function 2f(x) – h(x) will be calculated as,
E = 2f(x) – h(x)
E = 2( x + 2 ) - ( 1 / x-1)
E = 2x + 4 - (1/x-1)

Answer:
He buys 8 desks and 6 chairs can i have branliest
Step-by-step explanation:
Set up a system of equations
desks = y chairs = x
x+y=14
125x + 515y = 4870
Eliminate,
-125x -125y = -1750
125x + 515 y = 4870
390 y = 3120
y = 8
substitute in 8
x + 8 = 14
x = 6
Answer: $47.06 if you do not round or $47.07 if you are required to round up.
Step-by-step explanation:
$43.99× .07 = 3.0793
$43.99+ $3.07 = $47.06
(If you round up then follow below)
$43.99× .07= 3.0793 (the 9 would cause you to round the 7 up to 8)
$43.99+ $3.08= $47.07
