Topic 4 TEST REMEDIATION

Front

What is the elimination method in solving systems of equations?

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the other variable.

Front

How do you determine which number to multiply by in the elimination method?

Back

You multiply by a number that will make the coefficients of one variable the same (or opposites) in both equations, allowing for elimination.

Front

What does it mean for a solution to be a whole number combination in a system of inequalities?

Back

It means that the solutions consist of non-negative integers that satisfy the inequalities.

Front

What is a boundary line in the context of inequalities?

Back

A boundary line is the line that represents the equation of the inequality, dividing the coordinate plane into regions that satisfy or do not satisfy the inequality.

Front

What does it mean for a solution set to be above the boundary line?

Back

It means that the solutions to the inequality are located in the region of the coordinate plane that lies above the line representing the inequality.

Front

What is the significance of the inequality symbol in a system of inequalities?

Back

The inequality symbol indicates the relationship between the variables, showing whether one is greater than, less than, or equal to the other.

Front

How do you graph a system of inequalities?

Back

You graph each inequality on the same coordinate plane, shading the region that satisfies each inequality.

Front

What is the formula for the area of a circle?

Back

Front

How do you solve for a variable in a formula?

Back

To solve for a variable, you isolate it on one side of the equation using algebraic operations.

Front

What does it mean for every solution of one inequality to be a solution to the system?

Back

It means that if a solution satisfies one inequality, it also satisfies all inequalities in the system.
