What else can I help you with?
How do you know whether to use an open circle or a closed circle when graphing an inequality?
If the inequality is > or< then it is an open circle. If it is greater than or equal to or less than or equal to, it is a closed circle.
What is the purpose of using a circle graph?
In a circle graph it is easier to see shares of the total than in other kinds of graphs.
Why is it easier to circle your wrist than to lift one leg up and draw a circle in the air?
It is easier because the legs carry the whole weight of the body and if you lift it for a longer time your balance will go.
How is graphing a linear inequality different than graphing a linear equation?
In an inequality, you have to shade a side of a line to see show if the possible answers are greater than or equal to it
What is one purpose of a circle graph?
circle graphs create a visual picture of a proportion compared to a whole. Sometimes it is easier to see 25% of this, 15 % of that, and 60 % of something in a circle graph than to hear someone verbally say it to you. Also, you can easily compare two percentages together.
Why is graphing easier than using elimination or substitution?
Graphing is not necessarily easier than elimination or substitution. If you are good at drawing graphs, and do not like algebra, then graphing is easier. However, elimination and substitution are much faster, and graphing can often get awkward when working with more complicated formulae.
How do you know whether to use an open circle or a closed circle when graphing an inequality?
If the inequality is > or< then it is an open circle. If it is greater than or equal to or less than or equal to, it is a closed circle.
Why do you need a graphing calculator?
Graphing calculators are true to their name: they can graph out equaitions. Letting the calculator graph out equations is a lot easier than plotting and drawing your own graph, but you do not NEED a graphing calculator. Besides that, their functions are similar to other scientific caculators.
Why is graphing the solution of an inequality easier than listing all solutions?
so that you can easily tell what the answer is by extending the line on the graph instead of calculating it
What date did Johannes Kepler discover ellipses?
Kepler did not discover ellipses. In 1605 he discovered that the orbits of the planets were ellipses rather than perfect circles.

What are the advantages of a circle graph?
it is more easier to see which subject has more than the other

It is easier because the legs carry the whole weight of the body and if you lift it for a longer time your balance will go.
Why is measuring the diameter of a circle easier than measuring the its circumference?
Because the diameter is a straight line.
How is graphing a linear inequality different than graphing a linear equation?
In an inequality, you have to shade a side of a line to see show if the possible answers are greater than or equal to it
How is graphing an inequality different than graphing an equation?
Not greatly. To graph an inequality, you start off graphing the corresponding equality. It is only then that you select one side or the other (with or without the graph itself), as the region of interest.
