Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height

Front

How do you solve for x in the equation 2x + 3 = 11?

Back

Subtract 3 from both sides: 2x = 8. Then divide by 2: x = 4.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

Define a linear equation.

Back

An equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

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

Back

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

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the quadratic formula?

Back

x = (-b ± √(b² - 4ac)) / (2a) for the equation ax² + bx + c = 0.

Front

What is the difference between mean, median, and mode?

Back

Mean is the average, median is the middle value, and mode is the most frequent value.

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope and will never intersect.
