Sure you can substitute that. You just have to be careful to avoid division by zero - but the same may happen with other numbers as well. For example:
- If you have a denominator "x", then you can't substitute "x" by zero.
- If you have a denominator "x - 1", then you can't substitute "x" by 1, because if you do, the denominator will be zero.

How do you write -8 increased by the quotient of 13 and a number as variable expression?
-8 + 13/N, where N ≠0.
What is 20 plus 40x divided by 20x and are there any restrictions on the variable?
1/x + 2, provided x is not 0. If x is 0, the expression is undefined.
Can a term in an algebraic expression be zero?
Yes they can, for example quadratic expressions are often written in the form, ax^2+bx+c, where x is a variable, and a,b,c are constants. If you have an expression such as 5x^2 - 3, then clearly a=5, c=-3 and b=0
What is the difference between no solution and undefined?
undefined means you can not do the operation (5/0 is undefined) no solution refers to an equation not having an answer. a solution is a number which you can plug into the variable of an equation and get a true statement. So having no solution means there is no number which you can plug in and get a true statement. As a fraction is not an equation, but an expression it is not right to say that 5/0 has no solution. There is no variable in 5/0, nothing to plug into to get a true or false statement.

Explain how to find restrictions on the variable in a rational equation?
Substitute the variable in the denominator for a value that will make the denominator have a value of 0 or an imaginary number
What is a quadratic expression?
A quadratic expression is an expression which is written in the form ax2+bx+c, where a, b, and c represent constants, x represents a variable, and a is not equal to 0.
In the exponential expression a raise to negative n is a positive integer the variable a cannot be equal to zero Explain why this is so?
a^(-n) = (1/a)^nIf a is 0, the above expression would require division by 0, which is not defined.
How do you write -8 increased by the quotient of 13 and a number as variable expression?
-8 + 13/N, where N ≠0.
Is a expression the number multiplied to a variable?
An expression can be that, but it can also be a combination of such terms and other mathematical operations. For example, 3a + 27b^2/sin(27c) provided c is not 0.
What is 20 plus 40x divided by 20x and are there any restrictions on the variable?
1/x + 2, provided x is not 0. If x is 0, the expression is undefined.
What is the difference between a numerical expression and a algebraic expression?
Numerical expressions solely include numbers, while algebraic expressions may contain a variable like x. An example of a numerical expression is 1+2 and an example of an algebraic expression is 2x+3y=0.
What is a Variable expression for 5 divided by r?
A variable expression for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.
How can solve this 3p²-8p+4?
To find the value of ( 3p^2 - 8p + 4 ), you simply substitute the value of ( p ) into the expression. If ( p ) is a specific number or variable, plug it into the equation. For example, if ( p = 2 ): [ 3p^2 - 8p + 4 = 3(2)^2 - 8(2) + 4 ] [ = 3 \cdot 4 - 16 + 4 ] [ = 12 - 16 + 4 ] [ = 0 ] Therefore, when ( p = 2 ), ( 3p^2 - 8p + 4 = 0 ). If ( p ) is a variable and not a specific number, the expression ( 3p^2 - 8p + 4 ) represents a quadratic polynomial that can be factored or evaluated depending on the context or requirements of the problem.
