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
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

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.
Yes, the expression (3w - 7) is considered an open sentence because it contains a variable ((w)) and does not have a specific value assigned to it. Open sentences can take on different values depending on the value of the variable. In contrast, a closed sentence would have a specific value or statement, such as (3w - 7 = 0).
