An equation or inequality that contains one or more variables is?

Is yx3cubed plus x2squared a quadratic inequality?
No. This is not an inequality, because you need something > something_else, or less than or 'not equal' or 'greater than or equal', etc. Since it has an x cubed term, it is not a quadratic.
How do you tell a linear inequality from a quadratic inequality?
In a linear inequality the variable is only present raised to the first power (which is usually not explicitly shown). In a quadratic the square of the variable is present (or implied). The square can be implied in an inequality such as x + 1/x < 6 (x not 0) This is equivalent to x2 - 6x + 1 < 0
How do you solve a quadratic inequality when the expression is unfactorable?
Use the quadratic formula for the equality. Then, depending on the coefficient of x2 and the nature of the inequality [>, ≥, ≤, <], determine whether you need the open or closed intervals between the roots or beyond the roots.
How can the change in x affect the change in y in a inequality?
The answer depends on the nature of the inequality: whether it is linear, quadratic or has some other functional form.
How are quadratic inequalities different from linear inequalities?
A linear inequality is all of one side of a plane. A quadratic inequality is either the inside of a parabola or the outside.
How do tell the solution of an inequality?
Substitute the values of the variables into the inequality. If the inequality is true then they are a solution, if not, they are not.Substitute the values of the variables into the inequality.

What is the graph of a linear inequality in two variables called?
A bivariate linear inequality.

Define solution of a linear inequality in two variable?
If the equal sign in a linear equation in two variables is replaced with an inequality symbol, the result is a linear inequality in two variables. 3x-2y>7 x<-5

How can you write an inequality that is neither true nor false?
If you use a variable, or variables, with an equation, or with an inequality, it is neither true nor false until you replace the variables with specific values.
A square b square -2ab - 25?
a2b2 - 2ab - 25 is a quadratic expression in the variables ab. There is no equation or inequality in the question so there is nothing that can be solved. Because of the nature of the expression a and b cannot be separated in any meaningful way.
The solutions to a linear inequality are the points in the plane that make the inequality true?
Yes, and no. The solution set to an inequality are those points which satisfy the inequality. A linear inequality is one in which no variable has a power greater than 1. Only if there are two variables will the solution be points in a plane; if there are more than two variables then the solution set will be points in a higher space, for example the solution set to the linear inequality x + y + z < 1 is a set of points in three dimensional space.
