What do the shaded dots refer to in the graph of an inequality?
The shaded area of the graph of an inequality show the solution to the inequality. For example, if the area below y = x is shaded it is showing those ordered pairs which solve y < x.
What is different between absolute and percentage change?
If a variable goes from X to Y, change = Y-X.The absolute change = Y-X or X-Y, whichever is positive.The percentage change = 100*Change/X = 100*(Y-X)/X or 100*(Y/X - 1)
How to solve x plus y for graphing?
You cannot solve x plus y since that is an expression, not an equation (nor inequality).
What is the difference between expression and an inequality?
An expression is a collection of mathematical terms, connected by mathematical binary operations (such as +, - , * , /). An inequality is a comparison between two expressions. For example, x2 + 3x/4y - 2xy + 7 and 3x + sin(x)*ex - 29/x + sqrt(x+y3) - 4y/27, where x is not 0 are expressions in two variables, x and y. x2 + y < 4x is an inequality
Does slope equals change in y change in x?
yes, change in y over change in x equals slope
Find the graph of the inequality y -x plus 1?
"y - x + 1" is not an inequality. It is a simple expression. If you want something like "y - x + 1 > 0" that would be an inequality. Rephrase and resubmit.
What is the Cauchy-Schwartz inequality?
The Cauchy-Schwartz inequality is a mathematical inequality. It states that for all vectors x and y of an inner product space, the dot product of x and y squares is less than or equal to the dot product of x to itself multiplied by y to itself.
What is the comparison property of inequality?
It is commutative: If x is not equal to y then y is not equal to x. It is not reflexive, not transitive.
What do the shaded dots refer to in the graph of an inequality?
The shaded area of the graph of an inequality show the solution to the inequality. For example, if the area below y = x is shaded it is showing those ordered pairs which solve y < x.
What is an example of a inequality with no solution in the third quadrant?
Y > -x
How to separate an absolute inequality into the two cases?
|X| < y where y is non-negative, is equivalent to -X > -y and X < y.One way to think about it is that the distance of X from the origin - irrespective of direction - is less than y.
Is Inequality an equivalence relation?
No. It is not transitive. x ≠y and y ≠z does not imply that x ≠z
What is a solution of y - x -3?
y - x - 3 is an expression, not an equation nor an inequality. It cannot, therefore, have a solution.
What is different between absolute and percentage change?
If a variable goes from X to Y, change = Y-X.The absolute change = Y-X or X-Y, whichever is positive.The percentage change = 100*Change/X = 100*(Y-X)/X or 100*(Y/X - 1)
How to solve x plus y for graphing?
You cannot solve x plus y since that is an expression, not an equation (nor inequality).
What are linear inequalities in two variables?
The solution of a linear inequality in two variables like Ax + By > C is an ordered pair (x, y) that produces a true statement when the values of x and y are substituted into the inequality.
Which is a correct way of graphing the line y -x - 2?
y -x - 2 is not an equation (nor an inequality) and so there is no way to graph it.
