What does the symbol '≥' represent?

Back

The symbol '≥' means 'greater than or equal to'.

Front

How do you solve the inequality −4x + 10 ≥ 5x + 55?

Back

To solve, first isolate x: Add 4x to both sides and subtract 55 from both sides to get 10 - 55 ≥ 5x + 4x, which simplifies to -45 ≥ 9x, then divide by 9 to find x ≤ -5.

What does the symbol '>' represent?

Back

The symbol '>' means 'greater than'.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope in the equation y = 1.5x + 12?

Back

The slope is 1.5.

Front

What is the y-intercept in the equation y = 1.5x + 12?

Back

The y-intercept is 12.

Front

How do you calculate the linear regression equation from data?

Back

To calculate the linear regression equation, use statistical methods to find the best-fitting line through the data points, typically using the least squares method.

Front

What does the term 'solution set' mean in mathematics?

Back
