Read each question carefully and follow the instructions to identify and describe the variables. Show all your work where applicable.
1. In the equation y = mx + b, 'x' is typically referred to as the variable, and 'y' is the variable.
2. A variable whose value changes in response to another variable is called a variable.
3. A variable that represents a fixed, but unknown, value is often called a .
1. Which of the following best describes a constant in an algebraic expression?
A value that can change
A letter representing an unknown quantity
A fixed numerical value
The result of an equation
2. In the expression 3a + 5b - 7, which terms are considered variables?
3, 5, and 7
a and b
3a and 5b
All of them
1. Consider the formula for the area of a circle, A = πr². Identify the constant(s) and variable(s) in this formula. Explain your reasoning.
2. In a real-world scenario, if you are tracking the distance a car travels over time, what would be the independent variable and what would be the dependent variable? Justify your answer.
1. In the equation y = 2x - 5, both 'x' and 'y' are considered constants.
True
False
2. Parameters are quantities that remain constant within a specific problem but can change from one problem to another.
True
False
Match each term with its correct definition.
1. Independent Variable
a. A fixed numerical value
2. Dependent Variable
b. A variable whose value is determined by another variable
3. Constant
c. A variable whose value is not affected by other variables in the experiment
4. Parameter
d. A quantity that is fixed for a given problem but can change in different problems
