How do you solve the inequality x > 2 or x ≤ -3?

Back

To solve this inequality, you find the values of x that satisfy either condition: x can be any number greater than 2 or any number less than or equal to -3.

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

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

How do you convert the equation y = 2/3x - 6 to standard form?

Back

To convert to standard form, rearrange to get 2x - 3y = 18.

What is a binomial?

Back

A binomial is a polynomial with exactly two terms, such as 3x + 4.

Front

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the expression. For example, in 5x^3 + 2x^2, the degree is 3.

What is a fifth-degree binomial?

Back

A fifth-degree binomial is a binomial where the highest degree of the variable is 5, such as 17x^5 + 5xy^6.
