What is the distributive property?

The distributive property states that multiplying a sum by a number is the same as multiplying each addend individually and then adding up the products. In mathematical terms, it is expressed as a(b + c) = ab + ac, where a, b, and c are real numbers.

How do you solve equations with variables on both sides?

To solve equations with variables on both sides, you can start by simplifying each side of the equation and then combining like terms to get the variable terms on one side and the constant terms on the other side. Next, you can isolate the variable by performing inverse operations such as adding, subtracting, multiplying, or dividing to both sides until the variable is alone on one side. Finally, solve for the variable by performing the necessary arithmetic operations to find the solution.

What are the different types of factoring?

The different types of factoring include: invoice factoring, which involves selling invoices to a third party for a fee; purchase order factoring, where a third party provides financing based on a purchase order from a customer; and receivables factoring, which involves selling accounts receivable to a factor company in exchange for immediate cash. These types of factoring can help businesses improve cash flow and manage their working capital effectively.

What is the quadratic formula and how is it used?

The quadratic formula is used to find the roots of a quadratic equation in the form of ax^2 + bx + c = 0. It is given by x = (-b ± ?(b^2 - 4ac)) / 2a, where a, b, and c are the coefficients of the quadratic equation. By plugging in the values of a, b, and c into the formula, you can solve for the values of x that make the equation equal to zero, which are the roots or solutions of the quadratic equation.

How do you graph linear equations?

To graph a linear equation, start by determining the intercepts by setting one variable as zero at a time and solving for the other variable to find the x-intercept and y-intercept points. Plot these points on a coordinate system and then draw a straight line that passes through both points. This line represents the linear equation graph. Additionally, if the equation is in slope-intercept form (y = mx + b), you can use the slope (m) to find additional points by moving up or down and left or right accordingly. Connect these points to create the graph of the linear equation.

What are the different types of functions in algebra?

There are several types of functions in algebra, including linear functions, quadratic functions, polynomial functions, exponential functions, logarithmic functions, trigonometric functions, and rational functions. Each type of function has its own unique characteristics and can be represented in various forms to solve equations and analyze relationships between variables.

How do you solve inequalities?

To solve inequalities, you can follow the same rules as solving equations, but with one exception: if you multiply or divide both sides by a negative number, the direction of the inequality changes. Identify the variable, isolate it on one side of the inequality sign, then simplify and determine the values that satisfy the inequality based on the sign (<, >, ?, ?) and direction of the inequality. Finally, represent your solution on a number line or in interval notation.

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

The slope-intercept form of a linear equation is represented as y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept. This form makes it easy to identify the slope and y-intercept of a line on a graph.

How do you simplify expressions with exponents?

To simplify expressions with exponents, you can use the rules of exponents. When multiplying terms with the same base, you can add the exponents. When dividing terms with the same base, you subtract the exponents. When raising a power to another power, you multiply the exponents. Additionally, any base raised to the power of 0 equals 1, and any base raised to the power of 1 remains the same. By applying these rules consistently, you can simplify expressions with exponents effectively.

What are the properties of arithmetic and geometric sequences?

Arithmetic sequences have a common difference between consecutive terms and the nth term can be found using the formula an = a1 + (n-1)d, while geometric sequences have a common ratio between consecutive terms and the nth term can be found using the formula an = a1 * r^(n-1). The sum of the first n terms of an arithmetic sequence can be found using the formula Sn = n/2 * (2a1 + (n-1)d), and the sum of the first n terms of a geometric sequence can be found using the formula Sn = a1 * (1 - r^n) / (1 - r). These formulas are essential in understanding and solving problems related to arithmetic and geometric sequences.
