System of Equations Inequalities

Front

What does a solid line indicate in an inequality graph?

Back

A solid line indicates that the inequality includes the boundary line, meaning it has 'or equal to' in the symbol.

Front

In the equation 3x + 2y = 16, which variable should be solved for using substitution if the second equation is 7x + y = 19?

Back

You should solve for y in the second equation.

Front

Solve using substitution: x - 2y = 2 and 3x + 4y = 3. What is the solution?

Back

(1.4, -0.3)

Front

Which of the following is not a method to solve systems of equations? Elimination, Difference of Squares, Substitution, Graphing?

Back

Difference of Squares is not a method to solve systems of equations.

Front

Pick the ordered pair that is NOT a solution to the system: (0,0), (1,-1), (2,0), (4,-4).

Back

(0,0) is NOT a solution.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables.

Front

What does it mean to solve a system of equations graphically?

Back

It means to find the point(s) where the graphs of the equations intersect.

Front

What is the substitution method in solving systems of equations?

Back

The substitution method involves solving one equation for one variable and substituting that expression into the other equation.

Front

What is an inequality?

Back

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

Front

What does the symbol '>' represent in an inequality?

Back

The symbol '>' means 'greater than'.
