What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other.

Front

What does the symbol '>' mean in inequalities?

Back

The symbol '>' means 'greater than'. For example, x > 3 means x is greater than 3.

Front

What does the symbol '<' mean in inequalities?

Back

The symbol '<' means 'less than'. For example, x < -9 means x is less than -9.

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

Back

To solve, first combine like terms: -4x - 5x ≥ 55 - 10, which simplifies to -9x ≥ 45. Then divide by -9 (remember to flip the inequality sign), giving x ≤ -5.

Front

What is a solution set in mathematics?

Back

A solution set is the set of all values that satisfy a given inequality or equation.

Front

What is linear regression?

Back

Linear regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables by fitting a linear equation to observed data.

Front

What is the slope in the equation y = mx + b?

Back

In the equation y = mx + b, 'm' represents the slope, which indicates the steepness and direction of the line.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by 'b' in the equation y = mx + b.

Front

How do you interpret the solution x > 3?

Back

The solution x > 3 means that any value of x that is greater than 3 is a solution to the inequality.

Front

What is the difference between '≥' and '>' in inequalities?

Back

'≥' means 'greater than or equal to', while '>' means 'greater than'. The former includes the boundary value, while the latter does not.
