It could be an equation or an expression or a condition.
what a sufficent condition that shows a equation does not represent a linear function
The required condition is a*b ≠0. That is equivalent to the requirement that neither a nor b is 0.
The set of all the solutions of an equation or condition
it has two types
Guarded is better than Critical or Serious, and not as good as Stable. Usually, Guarded condition is on the good news side of the equation.
The formula written over the arrow in a chemical equation represents the catalyst or condition needed for the reaction to occur, but it is not consumed in the reaction itself.
In mathematics, to solve an equation is to find what values (numbers, functions, sets, etc.) fulfill a condition stated in the form of an equation (two expressions related by equality). These expressions contain one or more unknowns, which are free variables for which values are sought that cause the condition to be fulfilled. To be precise, what is sought are often not necessarily actual values, but, more in general, mathematical expressions. A solution of the equation is an assignment of expressions to the unknowns that satisfies the equation; in other words, expressions such that, when they are substituted for the unknowns, the equation becomes an identity
I need step by step on my graphic calculator on how to write an equation
If the regression is a perfect fit.
It is called a scientific law
Multicollinearity is the condition occurring when two or more of the independent variables in a regression equation are correlated.
