What is the formula to calculate sales tax?

Back

Sales Tax = Price × Sales Tax Rate

Front

Identify the equation that is different from the others: 2x + 1 = 5, x/3 = 3, x - 4 = 8, 5x = 25.

Back

x/3 = 3 is different because it involves division, while the others are linear equations.

Front

Translate the equation 2(x - 3) = 5x + 4 into a verbal sentence.

Back

Twice the difference of x and three equals five times x plus four.

Front

What type of function describes the cost of mailing a letter that increases at a constant rate?

Back

Linear function.

Front

What is a compound inequality?

Back

A compound inequality combines two inequalities, often using 'and' or 'or'.

Front

Solve the inequality: 3 < x + 1 ≤ 8. What is the solution set?

Back

The solution set is 2 < x ≤ 7.

Front

What does it mean for a function to be linear?

Back

A linear function has a constant rate of change and can be represented by a straight line on a graph.

Front

How do you find the slope of a linear equation in the form y = mx + b?

Back

The slope (m) is the coefficient of x, representing the rate of change.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows the relationship between expressions that are not necessarily equal.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.
