Can you solve3 x - y 1?
The equation you provided, 3x - y = 1, cannot be solved for any specific values of x and y without additional information. It is a linear equation in two variables, so it represents a straight line on a graph. To find a solution, you would need another equation or constraint.
What is the difference between a geometric constraint and a numeric constraint?
Dealing with engineering or CAD, a geometric constraint deals with constraints such as parallel or perpendicularity. A numeric constraint deals with distances and size. Width, length, and depth are examples of these.--------Geometric constraints are constant, non-numerical relationships between the parts of a geometric figure. Numeric constraints are number values, or algebraic equations that are used to control the size or location of a geometric figure :)
Features of primary key?
* In NOT NULL constraint the particular data cannot be NULL,* In UNIQUE constraint the same thing cannot be repeated, it must be unique,* The primary key is simply the combination of both these constraints.
How primary keys in database are denoted?
