What are 3 steps to graphing inequalities?
1.First change it to an equality. 2.Next, graph the line from step 1 3. Pick a test point and see if it is true or not.
Explain how to test whether the correct area has been shaded in the graph of an inequality?
Pick a sample point in the shaded area and plug it into the equation and see if it makes it true.
How to scketch graphs of functions?
the domain value is the x coordinate, and the range is the y coordinate. after graphing, do the vertical-line-test to see if it is a function or not.
What is the advantage that the method od substitution has over the graphing method of solving system of equations?
Substitution is a way to solve without graphing, and sometimes there are equations that are impossible or very difficult to graph that are easier to just substitute. Mostly though, it is a way to solve if you have no calculator or cannot use one (for a test or worksheet).
How many point taken off for each question on a 22 question test?
It depends on the test.
When graphing a linear inequality when can you NOT use (0 0) as a test point to determine which side of a boundary line to shade?
When the line goes through the origin like y>3x. Notice that there is no constant added to the end.
When you graph inequalities how do you know what to shade?
Pick a test point, (the origin is the most convenient unless the line of the inequality falls on it), and plug it into the same linear inequality. If the test point makes the inequality true, then shade that side of the line. If the test point makes the inequality false, then shade the opposite side of the line.
When graphing inequalities where can solutions be found?
I think that you are asking about the linear inequalities with two variables, so my answer is related to them. First, you have to draw the boundary line (be careful, if your inequality does not contain the equal sign, the boundary line will be a dashed line, because the points on the line are not solutions to the inequality), which divide the coordinate system in two half-planes. Second, you have to test a point on either sides of the line (the best point is the origin, (0, 0), if it is not on the boundary line). If that point satisfies the inequality, then there are all its solutions, otherwise they are to the opposite side.
For an inequality whose boundary is a hyperbola you should pick a test point that is located?
in between its two halves

What is rand on the graphing calculator and what does it do?
The calculator will run a certain number of random numbers to test a program.
Why is it usually only necessary to test one point when graphing an inequality?
One point in each interval. An entire interval, between two critical points, either fulfills, or doesn't fulfill, the inequality.For example, (x-3)(x+5) > 0; the corresponding equality is (x-3)(x+5) = 0, with the two critical points x = 3 and x = -5. The intervals that must be checked are x < -5, x between -5 and 3, and x > 3.
How do you test for water?
To test for water you need to boil it. It's boiling point is 100 degrees Celsius
I am taking my drivers test for the first time and need to know what i need to know for the test.?
For your driving test, you should know how to parallel park and do a 3 point turn. As far as tips for the big for the driving test, remember to just relax and breathe.

How do you graph -6 is greater than x plus 5 as an inequality on a number graph?
The inequality -6 > x+5 can be rewritten -11 > x (by subtracting five from each side) or rather x < -11. To graph this on a number line, draw an open circle over the number -11 (if the inequality included "or equal to" the circle would be filled in). Then draw a line/arrow coming out of the circle over the number line. The line should only be drawn over the portion of the number line that makes the inequality true. For instance, choose a test point. When x is -20, the inequality is true: -20 < -11. So in this case, the arrow coming out of the open circle will point to the left, in the direction that the number line is getting smaller.
