• Area = length - width.

• Area = length ÷ width.

What is the difference between a rational and an irrational number?

• Rational numbers can be expressed as a fraction, while irrational numbers cannot.

• Irrational numbers can be expressed as a fraction, while rational numbers cannot.

• Rational numbers are always whole numbers, while irrational numbers are decimals.

What is the Pythagorean theorem?

• In a right triangle, a² + b² = c², where c is the hypotenuse.

• In any triangle, the sum of the angles equals 180 degrees.

• The area of a circle is πr², where r is the radius.

• The relationship between the sides of a triangle is given by a² + b² = c, where c is the longest side.

If y varies inversely as x, and y = 4.5 when x = 10, what is x when y = 5?

• x = 7

• x = 8

• x = 9

• x = 10

What is the process of solving a linear equation?

• Isolate the variable on one side of the equation using inverse operations.

• Add the same number to both sides of the equation.

• Multiply both sides of the equation by the same number.

• Graph the equation to find the solution.

What is the definition of a function?

• A relation where each input has exactly one output.

• A set of ordered pairs with no restrictions.

• A collection of inputs and outputs that can be random.

• A mathematical operation that combines two numbers.

What is the slope-intercept form of a linear equation?

• y = mx + b, where m is the slope and b is the y-intercept.

• y = ax^2 + bx + c, which is the quadratic form.

• y = mx + c, where m is the slope and c is the y-intercept.

• y = b/x + a, which is the inverse form.
