Positive statements are objective assertions that can be tested and validated through evidence, while value judgments express subjective opinions about what is desirable or undesirable. Therefore, positive statements do not involve value judgments; they focus on facts and what "is," rather than what "ought to be."

What statements contain a variable Check all that apply.?
Statements that contain a variable typically include expressions or equations where a symbol (often a letter) represents an unknown or changing value. For example, equations like "x + 5 = 10" or expressions like "y = 2a + 3" contain variables (x, y, a). In contrast, statements with fixed numbers, such as "5 + 3 = 8," do not contain variables. To identify variable-containing statements, look for instances of letters or symbols that are not assigned a specific numerical value.
Can numerical expressions have the same value?
Yes, numerical expressions can have the same value. For example, the expressions 2+3 and 5 both have the value of 5. Similarly, the expressions 2x3 and 6 both have the value of 6. In general, any two numerical expressions that evaluate to the same number will have the same value.
What are expressions and equations?
Expressions are mathematical combinations of numbers, variables, and operations (like addition or multiplication) that do not include an equality sign, such as (3x + 2). Equations, on the other hand, are statements that assert the equality of two expressions, typically featuring an equal sign, such as (2x + 3 = 7). While expressions can be simplified or evaluated, equations can be solved to find the value of the unknown variable.
When two expressions have the same value they are?
equivalent
Does an algebraic expressions have a single value?
Not necessarily.
Which of these expressions always represents a negative value Which of these expressions always represents a positive value?
None of "these" expressions represent anything!
What is the positive and normative analysis in economics?
A positive analysis is a statement of what is. The truth. Purely descriptive statements or scientific predictions.A normative analysis is a statement of what ought to be. Analysis involving value judgments.
Is there a number that can be negative or positive?
No single number can be negative or positive. There are equations or expressions whose value can be either but not a number.
What is positive economics and negative economics?
Positive economics deals with objective analysis and factual statements about economic phenomena, focusing on what is or what will be based on evidence and data. It seeks to describe and explain economic behavior without making value judgments. In contrast, normative economics involves subjective opinions and value-based statements about what ought to be, addressing questions of fairness, equity, and policy recommendations. Together, these two branches help to understand both the functioning of economies and the ethical implications of economic choices.

What are expressions that have the same value no matter what x represents called?
algebraic expressions
What are math statements that contains variables?
math statements that contain variables are expressions or equations that have a letter or symbol that represents a number or value. for example, if (2+N=7), N is the variable and N=5 hope this helps
What are expressions that have the same value?
Equivalent expressions.
Can numerical expressions have the same value?
Yes, numerical expressions can have the same value. For example, the expressions 2+3 and 5 both have the value of 5. Similarly, the expressions 2x3 and 6 both have the value of 6. In general, any two numerical expressions that evaluate to the same number will have the same value.
What is a positive theory?
A positive theory seeks to understand how something is or how it operates, without making value judgments or prescribing how it should be. It aims to describe and explain phenomena based on empirical evidence and facts, rather than opinions or beliefs.
What are expressions and equations?
Expressions are mathematical combinations of numbers, variables, and operations (like addition or multiplication) that do not include an equality sign, such as (3x + 2). Equations, on the other hand, are statements that assert the equality of two expressions, typically featuring an equal sign, such as (2x + 3 = 7). While expressions can be simplified or evaluated, equations can be solved to find the value of the unknown variable.
Examples of positive and normative statements?
Positive economics deals with objective explanation and the testing and rejection of theories. Positive statements are objective statements that can be tested or rejected by referring to the available evidence.For example:A rise in consumer incomes will lead to a rise in the demand for new cars.A fall in the exchange rate will lead to an increase in exports overseas.Normative statements express an opinion about what ought to be. They are subjective statements rather than objective statements - i.e. they carry value judgments.For example:The level of duty on petrol is too unfair and unfairly penalizes motorists.The government is right to introduce a ban on smoking in public places.
