What is the difference between an equation and an inequality?
An equation is a mathematical statement where two expressions are equal to each other, such as x = 5. On the other hand, an inequality is a mathematical statement where two expressions are not equal, typically represented by symbols such as < (less than), > (greater than), ? (less than or equal to), or ? (greater than or equal to), such as x > 5. Inequalities represent a range of values that satisfy the given conditions, whereas equations represent a single value where the expressions are equal.
How do you solve a linear equation with variables on both sides?
To solve a linear equation with variables on both sides, start by simplifying each side to get the variable terms on one side and the constant terms on the other. Then, combine like terms and isolate the variable term by performing inverse operations such as addition, subtraction, multiplication, and division. Once you have isolated the variable, solve for its value by performing the necessary operations. Finally, check your solution by substituting it back into the original equation to verify its accuracy.
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 intersects the y-axis. This form is useful for graphing and analyzing linear relationships between variables.
How do you simplify expressions with exponents?
To simplify expressions with exponents, you can use the rules of exponents, such as the product rule (x^a * x^b = x^(a+b)), the quotient rule (x^a / x^b = x^(a-b)), and the power rule ((x^a)^b = x^(a*b)). You can also simplify by combining like terms and reducing fractions when possible. Remember to follow the order of operations and always look for opportunities to reduce the expression by applying the rules of exponents.
What is the distributive property and how is it used in algebraic expressions?
The distributive property states that for any real numbers a, b, and c, a(b + c) = ab + ac. In algebraic expressions, the distributive property is used to simplify expressions by distributing a factor across the terms within parentheses. This allows us to combine like terms and make the expression easier to work with or evaluate. For example, in the expression 3(2x + 4), the distributive property can be used to multiply 3 by both the terms inside the parentheses, resulting in 6x + 12.
How do you solve a system of linear equations using the substitution method?
To solve a system of linear equations using the substitution method, you start by isolating one of the variables in one of the equations. Then, substitute the expression for that variable into the second equation. This will create a new equation with only one variable, which you can solve for. Finally, substitute the value found back into one of the original equations to solve for the other variable. This process allows you to find the values of both variables and solve the system of equations.
What is the difference between a factor and a multiple in algebra?
In algebra, a factor is a number or algebraic expression that divides evenly into another number or expression, while a multiple is the result of multiplying a number by an integer. Factors can be multiplied together to obtain a given number or algebraic expression, while multiples are obtained by multiplying a number by any integer. In simpler terms, factors divide a number evenly, while multiples are the product of multiplying a number by a certain value.
How do you graph a linear equation using its slope and y-intercept?
To graph a linear equation using its slope and y-intercept, start by plotting the y-intercept on the y-axis. Then, use the slope to find another point on the line by moving up or down based on the rise (numerator of the slope) and right or left based on the run (denominator of the slope) from the y-intercept. Connect these two points with a straight line to graph the linear equation.
What is the quadratic formula and when is it used to solve a quadratic equation?
The quadratic formula is -b ± ?(b² - 4ac) / 2a, where a, b, and c are coefficients of a quadratic equation in the form ax² + bx + c = 0. It is used to find the roots of a quadratic equation when factoring or completing the square methods are not practical or possible. By substituting the values of a, b, and c into the formula, one can solve for the values of x that satisfy the quadratic equation.
How do you solve a word problem using algebraic equations and inequalities?
To solve a word problem using algebraic equations and inequalities, first, define variables to represent unknown quantities. Write equations or inequalities based on the given information in the problem. Translate the problem into mathematical expressions using these equations or inequalities, and then solve for the variables by simplifying and isolating them. Lastly, check the solution by plugging it back into the original problem to ensure it satisfies all conditions.
