What is a variable in algebra?

In algebra, a variable is a symbol used to represent an unknown or unspecified number. It is usually represented by a letter, such as x, y, or z, and can take on different values in mathematical expressions and equations. By using variables, algebra allows for the exploration and manipulation of mathematical relationships and patterns without knowing the specific numerical values involved.

How do you solve for a variable in an equation?

To solve for a variable in an equation, isolate the variable on one side of the equation by using inverse operations to manipulate the equation. This means performing the same operation on both sides of the equation to maintain its balance. Keep simplifying the equation until you have the variable isolated on one side and a numerical value on the other side, giving you the solution for the variable.

What is a term in an algebraic expression?

In an algebraic expression, a term is a single mathematical entity that can consist of constants, variables, coefficients, and exponents, separated by mathematical operators such as addition or subtraction. Each term in an algebraic expression can be seen as a building block that contributes to the overall result when the expression is simplified or evaluated.

What is the difference between an equation and an inequality?

An equation is a mathematical statement that shows that two expressions are equal, such as 2x + 5 = 9. An inequality, on the other hand, shows a relationship between two expressions that may not be equal, using symbols like < (less than), > (greater than), ? (less than or equal to), or ? (greater than or equal to), such as 3x + 4 < 10. Inequalities indicate a range of possible values that make the statement true, while equations represent a specific value that makes the statement true.

How do you simplify an algebraic expression?

To simplify an algebraic expression, combine like terms by adding or subtracting coefficients of the same variables. Also, use the distributive property to factor out common factors, simplify fractions, and if necessary, apply rules of exponents or logarithms to further simplify the expression. Make sure to follow the order of operations (PEMDAS) to simplify expressions correctly.

What is the distributive property in algebra?

The distributive property in algebra states that when multiplying a number by a sum or difference of two or more numbers, the result is the same as if each number in the sum or difference was multiplied by the original number separately and then added or subtracted. This property is often expressed as a(b + c) = ab + ac or a(b - c) = ab - ac, where 'a', 'b', and 'c' are variables or constants.

How do you solve a system of linear equations?

To solve a system of linear equations, you can use methods such as substitution, elimination, or matrix operations. First, write down the equations and identify the variables. Then, use one of the methods mentioned to isolate and solve for the variables. Follow the steps systematically and consistently until you find the values that satisfy all equations simultaneously, representing the solution to the system of linear equations.

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 of the line.

What is the difference between a polynomial and a monomial?

A polynomial is a mathematical expression consisting of variables and coefficients that are combined using addition, subtraction, and multiplication, while a monomial is a specific type of polynomial that consists of only one term. In other words, a monomial is a special case of a polynomial where there is only one term in the expression, while a polynomial can have multiple terms.

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

To find the domain and range of a quadratic function, identify the values of x that are permissible inputs (domain) by considering the restrictions on x-values in the quadratic equation. The domain of a quadratic function is typically all real numbers unless there are specific restrictions mentioned. The range can be determined by analyzing the vertex of the quadratic function, which represents the maximum or minimum point depending on the direction of the parabola. The range is all real numbers greater than or equal to the minimum (if it opens upwards) or less than or equal to the maximum (if it opens downwards) y-value of the vertex.
