What is an open sentence in math?
Every sentence to which standard logic applies has exactly one of the truth values (that is, either true or false, but not both). No sentence can be both true and false.An equation is a statement that sets two mathematical expressions equal.When both sides of an equation are numerical expressions (contain no variables), the equation is a closed statement. This means the equation can be assigned a truth value.Example:2 + 5 = 7 true 2(3) - 2 = 6 falseIf an equation is neither true nor false, the equation is an open sentence.An open sentence is a mathematical statement with one or more variables. When variables are present in an equation, the solution is unknown. The set of numbers that you use to represent the variable(s) is called the replacement set. The solution set is found when any value(s) for the variable from the replacement set makes the equation a true statement.Examples: 3x+6=20; 12n-5=45; 6a+2b+7c=84; 4p>25; 9s+24
Is -8 plus 3 equals -8 plus 3 true or false?
Is |-8|+|3|=|-8+3| true or false?
The absolute value of -3 is 3 ture or false?
True.
The sum of 3 odd numbers is odd-true or false?
True.
Is this equation true or false 3 x - 4 Is?
False because it does not have an equality sign and so therefore it is not an equation.
Does a solution to an equation make the equation true or false?
A solution to an question makes the equation true. For example a solution to the equation 3x = x + 6 is x = 3, since 3(3) = 3+6.
Is the graph of the equation x equals 3 is a horizontal line true or false?
False. X = 3 is a vertical line.
Is this statement true or false In the equation y equals 3 over X's the constant of variation is X's?
False.
Is this true 5-3-15-(3-1)?
The question contains an expression - not an equation nor an inequality. An expression cannot be true or false.
What is a linear equation that is not true for even one real number and therefor has no solution?
A linear equation in one variable. Case 1: A conditional equation: True only for a value of the variable. Ex. x + 2 = 3, True only when x is 1. Case 2: Identity Equation: Always true. Ex. x + 2 = x + 2, True for any value of x. Case 3: x + 1 = x + 5, False for any value of x. We call a solution any value of the variable that satisfies the equation, meaning if we replace the variable with that value, the equation becomes a true statement. Example: -2(x -3) = 8 - 2x -2x + 6 = 8 - 2x (add 2x and subtract 6 to both sides) 0 = 2 False. Since this equation, which is equivalent to the original equation, is false, then the original equation is also false. Meaning, there is no real number for x that could satisfy the equation. So there is no solution to the equation.
Is 21 a solution for x plus 3 equals 24 True or False?
21 is the only solution of that equation.
Why an open sentence always has at least one variable?
An open sentence is neither true nor false. It depends on the value of the variable. If you had 5=3 that would be a closed sentence which is false. If you had 5=5 that would be a closed sentence which is true. If you had x=3 then it is open to whether the x is a 5 or a 3.
What is a solution to an open sentence?
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
Is this true 5-3-5-(3-1)?
No, the expression 5-3-5-(3-1) evaluates to 3, not zero.
What examples of a true and a false equation?
False: -2=3, because clearly, -2 is not 3 or else -2 would be called 3. 1/2 =5, same concept True: -2=-2 -2x=-2x x=x 1/2=.5
Is the answer to this question true or false (0 -2) is a solution of the equation 2x and ndash 3y 6.?
If you mean 2x -3y = 6 then it is true and so is (3, 0)
