An open number sentence is a sentence which contains a variable. A variable is a unknown number but replaced with a letter and can be on either side of an equals sign.
3x + 8 = 4x + 23x - 4x = 2 - 8-x = -6x = 6
You need to clarify the function AND provide an interval.
an open circle on a number line means the answer is just less than or greater than (< or >), but a closed circle means the answer is less than or equal to, or greater than or equal to (< or > with a line under it)
A value that satisfies an open sentence is called a solution or a root of the open sentence.
a solution
To determine if a given value is a solution to an open sentence in math, substitute the value into the equation or inequality. Then, simplify the expression to see if it holds true. If the resulting statement is valid (e.g., a true equation or a satisfied inequality), the value is a solution; if not, it is not a solution.
an open sentence can be either true or false, depending on what values are substituted for the variables. A SOLUTION of an open sentence with on variable is a value that makes the sentence true. The solution of the equation x+3=5 is 2. One solution of the inequality x-1>4 is 6, and there are many more solutions. hope this helps

domain
An open number sentence is a sentence which contains a variable. A variable is a unknown number replaced with any letter and can appear on either side of the equals sign.
no it is a closed equation.
No, it is a FALSE statement.
3x + 8 = 4x + 23x - 4x = 2 - 8-x = -6x = 6
Yes, an open sentence must contain a variable, as it is an expression that can be true or false depending on the value of that variable. For example, in the open sentence "x + 2 = 5," the variable "x" represents an unknown value that can change the truth of the statement. Without a variable, the sentence would be a closed statement with a definitive truth value.
