What are the properties of real numbers?

Real numbers are closed under addition and multiplication, meaning that the sum and product of two real numbers is always another real number. They are also commutative and associative under addition and multiplication. Real numbers have an identity element of 0 for addition and 1 for multiplication, and each real number has an additive inverse. Additionally, real numbers have a total order, meaning that any two distinct real numbers can be compared using the less than or greater than symbols.

How do you solve a linear equation?

To solve a linear equation, isolate the variable by using inverse operations to move constants and coefficients from one side of the equation to the other. Start by simplifying both sides of the equation, then use addition, subtraction, multiplication, and division to manipulate the equation until the variable is isolated on one side. Finally, solve for the variable by performing the necessary operations to find its value.

What is the difference between a monomial, binomial, and trinomial?

A monomial is an algebraic expression consisting of a single term, a binomial is an algebraic expression consisting of two terms, and a trinomial is an algebraic expression consisting of three terms. Each term in these expressions is separated by addition or subtraction.

How do you factor a quadratic expression?

To factor a quadratic expression, you need to find two binomials that, when multiplied together, result in the original quadratic expression. This can be done by using the factoring techniques like grouping, the difference of squares, or the quadratic formula. Start by looking for common factors and then proceed to find two numbers that multiply to the constant term and add up to the coefficient of the linear term. Once you find these numbers, you can rewrite the quadratic expression as a product of two binomials.

What is the Pythagorean Theorem and how is it used?

The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, it can be written as a² + b² = c², where c represents the length of the hypotenuse, and a and b represent the lengths of the other two sides. This theorem is used to calculate the length of a missing side in a right-angled triangle when the lengths of the other two sides are known. It is also fundamental in various fields such as mathematics, physics, engineering, and architecture for solving problems related to angles, distances, and measurements.

How do you simplify expressions involving exponents?

To simplify expressions involving exponents, you can use the rules of exponents. When multiplying terms with the same base, add their exponents; when dividing terms with the same base, subtract their exponents; when raising a power to a power, multiply the exponents; when a term has a negative exponent, move it to the denominator to make it positive; and any base raised to the power of 0 equals 1. These rules can help you simplify expressions efficiently by manipulating the exponents to consolidate terms and reduce complexity.

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

The slope-intercept form of a linear equation is y = mx + b, where y represents the dependent variable, x represents the independent variable, m is the slope of the line, and b is the y-intercept, which is the point where the line crosses the y-axis. This form makes it easy to identify the slope and y-intercept from the equation.

How do you find the domain and range of a function?

To find the domain of a function, identify all the possible input values that the function can accept without any restrictions. This means considering any restrictions on the variables, such as avoiding division by zero or negative values under square roots. For the range, determine all the possible output values that the function can produce by evaluating the function for all values in the domain. Pay attention to the behavior of the function as it approaches positive and negative infinity to determine the full extent of the range.

What is the difference between an equation and an inequality?

An equation is a statement asserting that two mathematical expressions are equal, while an inequality is a statement that one expression is greater than, less than, or not equal to another expression. Equations typically have a single solution or a set of solutions that make the statement true, whereas inequalities represent a range of values that satisfy the inequality. Equations are used to find specific values, while inequalities are used to represent relationships between values.

How do you graph linear equations on a coordinate plane?

To graph linear equations on a coordinate plane, you first need to arrange the equation into the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Next, plot the y-intercept point on the y-axis. Use the slope to find additional points by moving along the line in the direction determined by the slope (rise over run). Connect the points with a straight line to represent the linear equation on the coordinate plane.
