To evaluate a variable expression, first substitute the values of the variables with their corresponding numerical values. Next, perform the arithmetic operations in the correct order, following the rules of parentheses, exponents, multiplication and division, and addition and subtraction (PEMDAS/BODMAS). Finally, simplify the expression to obtain the final value.

What statement best describes the excluded values of a rational expression?

The excluded values of a rational expression are the values of the variable that make the denominator equal to zero. These values are not in the domain of the expression, as division by zero is undefined. To identify excluded values, set the denominator equal to zero and solve for the variable. Any solution to this equation represents an excluded value.


What best describes the algebraic expresson 15x plus 8?

The algebraic expression (15x + 8) is a linear expression, as it represents a straight line when graphed on a coordinate plane. It consists of a term with a variable ((15x)) and a constant term ((8)). The coefficient (15) indicates the slope, while (8) is the y-intercept. Overall, it combines both a variable and a constant in a straightforward manner.


Is the best describes the English expression the product of two and a number minus eleven?

The English expression "the product of two and a number minus eleven" can be mathematically represented as ( 2x - 11 ), where ( x ) is the variable representing "a number." This expression indicates that you first multiply the number by two and then subtract eleven from the result. It effectively combines multiplication and subtraction in a single algebraic statement.

Static Variable : If we declare a variable as Static , then it wont have the permission to access that variable through out the program and u have to use it inside the class or object which u declared itself.
