Example Question #1 : How To Graph An Inequality With A Number Line
Which line plot corresponds to the inequality below?
A closed circle indicates "greater than or equal to" or "less than or equal to," while and open circle indicates "greater than" or "less than". We can tell from the inequality that our line plot will only have closed circles, as the only symbol is "greater than or equal to."
Subtract from both sides.
Divide both sides by .
Our plot will show a closed circle on , and extend infinitvely in the positive direction.
Example Question #1 : How To Graph An Inequality With A Number Line
An open circle indictes "less than" or "greater than," while a closed circle indicates "greater than or equal to" or "less than or equal to".
This number line includes values that are less than or greater than or equal to . Note how has an open circle, while has a closed circle.
Example Question #2 : Complex Numbers
Divide:
The answer must be in standard form.
Multiply both the numerator and the denominator by the conjugate of the denominator which is which results in
The numerator after simplification give us
The denominator is equal to
Hence, the final answer in standard form =
