5x > -20 divide both sides by 5;
x > -4
On a number line graph all real numbers to the right of -4 and use an open dot at -4 to indicate that -4 is not a solution.

What is the equal to or greater then symbol on a graph?
If the graph is a two-dimensional plane and you are graphing an inequality, the "greater than or equal to" part will be shown by two things: (1) a solid, not a dotted, line--this part signifies the "or equal to" option--and (2) which region you shade. Shade the region that contains the points that make the inequality true. By shading that region, you are demonstrating the "greater than" part.
How do you write an algebraic inequality for... all numbers x are greater than or equal to negative four?
x ≥ -4
Is -4 a solution to the inequality x greater than or equal to 4?
No. If x greater than or equal to 4 it must be 4 or higher; negative 4 is lower than 4
How do you graph an inequality with a greater than sign?
Draw the graph of the corresponding equality. This will divide the Cartesian plane into two parts.Evaluate the inequality for the origin, O - the point (0,0). Any point will do, but O it is easy to evaluate it there.It the inequality is true, then the part of the plane that contains the origin is the valid region whereas if the inequality is false, the other region is valid.
How do you graph the inequality w is greater than or equal to 5?
The answer depends on what space you are working in. In 1-dimensional space, it would be like the number line and the relevant part of the graph would be all point at or to the right of the value 5.
What side of the graph will the shaded part be if the inequality is greater than?
If it is y is greater than then it is above the line. If it is x is greater than then it is to the right.
Find the graph of the inequality y plus 2 -x - 6?

When will the graph of an equation inequality be a dotted line?
The line is dotted when the inequality is a strict inequality, ie it is either "less than" (<) or "greater than" (>). If there is an equality in the inequality, ie "less than or equal to" (≤), "greater than or equal to" (≥) or "equal to" (=) then the line is drawn as a solid line.
What happens when both sides of a less than inequality are multiplied or divided by a negative number?
The inequality sign becomes greater than (>).
Write an inequality for each sentence Graph the solutions of each inequality on a number line r is not greater than five?
r <= 5.
Do you only flip the inequality when you divide by a negative number?
Yes you do, you also flip the inequality sign if you multiply by a negative # The > and < signs are strictly the "Greater than" and "Less than" signs. The inequality sign is an = with a / stroke through it. If you divide an inequality by -1 it remains an inequality.
What do you do with your inequality if you divide by both sides by a negative number?
If two sides of an inequality are multiplied (or divided) by a negative number, you have to invert the sign. For example, a "less-than" sign becomes a "greater-than" sign.
What would x is greater than or equal to negative six look like as a graph?
At negative six on the x-axis, draw a vertical line. That line will be a solid line because we have that x is greater than OR EQUAL TO negative six. Then shade the right half of the graph -- which is where x has a value that is to the right (greater than) negative six
What inequality is greater than or equal to -5?
An inequality has no magnitude. A number can be greater than or equal to -5, but not an inequality.
How can you graph an inequality?
You have to graph an inequality on a number line. For example, x>3.The number 3 on the number line gets an open circle around it, and a line is extended to all the other possible equations.There is an open circle if it is a "greater than or less than" sign, and there is a shaded circle if there is "greater than or equal to, or a less than or equal to" sign.
