What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the set of values that satisfy all equations in the system.

How do you solve a system of linear equations using substitution?

Back

To solve a system using substitution, solve one equation for one variable, then substitute that expression into the other equation to find the value of the second variable.

What is the graphical representation of a system of equations?

Back

The graphical representation of a system of equations is the point(s) where the graphs of the equations intersect, which represents the solution(s) to the system.

What is an arithmetic sequence?

Back

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant.

How do you find the nth term of an arithmetic sequence?

Back

The nth term of an arithmetic sequence can be found using the formula: a_n = a_1 + (n-1)d, where a_1 is the first term and d is the common difference.

What is the formula for the sum of the first n terms of an arithmetic series?

Back

The sum of the first n terms of an arithmetic series is given by S_n = n/2 * (a_1 + a_n), where a_1 is the first term and a_n is the nth term.

What does it mean for a function to be reflected across the y-axis?

Back

A function is reflected across the y-axis if for every point (x, y) on the graph, the point (-x, y) is also on the graph.

How do you determine the equation of a transformed quadratic function?

Back

To determine the equation of a transformed quadratic function, identify the transformations applied (e.g., shifts, reflections) and apply them to the standard form of the quadratic equation.

Front

What is the common difference in an arithmetic sequence?

Back

The common difference in an arithmetic sequence is the constant amount that each term increases or decreases by from the previous term.

How do you solve a system of equations using elimination?

Back

To solve a system using elimination, manipulate the equations to eliminate one variable, allowing you to solve for the other variable.
