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 solve for x in the equation 7x - 4x = 27?

Back

Combine like terms to get 3x = 27, then divide both sides by 3 to find x = 9.

Front

What does it mean to simplify an expression like 2x + 3 + 9x + 2?

Back

It means to combine like terms to get 11x + 5.

Front

How do you solve the equation 6x + 3x = 18?

Back

Combine like terms to get 9x = 18, then divide both sides by 9 to find x = 2.

Front

If a = 5 and b = 6, how do you calculate ab - b?

Back

First calculate ab = 5 * 6 = 30, then subtract b: 30 - 6 = 24.

Front

What is a variable in mathematics?

Back

A variable is a symbol, often a letter, that represents a number in an equation or expression.

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions.

Front

What does it mean to combine like terms?

Back

Combining like terms means to add or subtract terms that have the same variable raised to the same power.

Front

What is the value of x in the equation 2x + 3 = 11?

Back

Subtract 3 from both sides to get 2x = 8, then divide by 2 to find x = 4.

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac.
