The graph of a linear inequality in one variable is a number line. Use an open circle for < and > and a closed circle for ≤ and ≥. The graph for x > -3 The graph for x ≥ 2 Inequalities that have the same solution are called equivalent. There are properties of inequalities as ...
x≥−3x≥−3. This translates to all the real numbers on the number line that are greater than or equal to -3.Each of these graphs begins with a circle—either an open or closed (shaded) circle. This point is often called the end point of the solution. A closed, or shaded, ...

A variable is a term that represents an unknown number or unknown value or unknown quantity. These are used in the case of algebraic expression or algebra. For example, x+9=4x+9=4 is a linear equation where xx is a variable and 99 and 44 are constants. Hence, an algebraic term refe...

rough this process, our concept of number has been stretched and expanded. What was once something that match p with the ngers on our hand becomes something that while still useful is not as easy to visualize and represent. During our journey from counting numbers to fractions to real ...
