What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the set of values that satisfy all equations simultaneously.

How do you represent the total cost of items in a system of equations?

Back

The total cost can be represented as a linear equation where the coefficients represent the price of each item multiplied by the quantity.

Front

What does it mean for a relation to be a function?

Back

A relation is a function if each input (x-value) is associated with exactly one output (y-value).

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable. It shows how steep the line is.

Front

How do you solve a quadratic function for a specific value?

Back

To solve a quadratic function for a specific value, substitute the value into the function and simplify to find the output.

Front

What is the process for solving inequalities?

Back

To solve inequalities, isolate the variable on one side of the inequality sign, applying the same rules as for equations, but reverse the inequality sign when multiplying or dividing by a negative number.

Front

What is a function table?

Back

A function table lists pairs of input values and their corresponding output values, helping to visualize the relationship defined by the function.

Front

What is the difference between a relation and a function?

Back

A relation is any set of ordered pairs, while a function is a specific type of relation where each input is paired with exactly one output.

Front

How do you determine if a table represents a function?

Back

Check if any x-value is repeated; if it is, the table does not represent a function.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.
