x ≥ - 10.2
On a number line graph all real numbers to the right of -10.2. Use a closed dot to indicate that -10.2 is a solution.
Same , equal
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.
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.
A straight line graph with negative slope slants downward from left to right.
No.
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
to graph in equaltities in two variables, you graph the two numbers and/or variables. then you look at the sign to see if its greater than, less than, greater than or equal to, or less than or equal to and you graph the line as dashed or a solid
Same , equal
An equation has an equal sign, which means that we know what the variable is equal to :)
x=9
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.
Equations are statements that state two expressions are equal, while inequalities are statements that state two expressions are not equal, meaning one is greater or less than the other. The graph of the solution set of an equation is a line or a curve, while the graph of the solution set of an inequality is a region at one side of the boundary line or curve obtained by supposing that the inequality was an equation.
If the discriminant is negative, the equation has no real solution - in the graph, the parabola won't cross the x-axis.
A solid line with a slope of -1/3 crossing the y-axis at 4 and shaded above the line.
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.
To graph the solution set for b is not equal to 0 on a number line, you would first place a filled-in circle at 0 to indicate that 0 is not included in the solution set. Then, draw a ray extending to the left and another extending to the right, indicating that the set includes all numbers except 0. No other markings or filled-in circles are needed since all numbers, positive or negative, except 0, are part of the solution set.
