No. A value that is unknown may not be a variable but simply a constant whose value needs to be calculated.
The variable "I" in algebra can represent any unknown quantity or value. It is commonly used to represent interest in mathematical equations related to finance or economics. However, "I" can refer to any unknown in an equation and its meaning depends on the specific context in which it is used.
a variable (an unknown number/ any number).
No, it is called a constant. For example, in algebra, all number values are constants.
If the value of a function cannot be determined for any value of the independent variable, then, the value the function seems to be approaching would be its limiting value for that particular value of the independent variable.

yes
True.
you can change the value of x to any new value and it has no effect on the value of y.
Simply reassign the value. If you have a variable $x, and you add 1 to it, you can store the value by stating $x = $x+1;
In an equation "x" is the value assigned to one of the unknown quantities in the equation. (example: y= mx+b). X is often used to describe any unknown thing, as in x-ray which were named this because the nature of the ray was initially unknown.
The variable "I" in algebra can represent any unknown quantity or value. It is commonly used to represent interest in mathematical equations related to finance or economics. However, "I" can refer to any unknown in an equation and its meaning depends on the specific context in which it is used.
Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.
Temperature change is a continuous and interval variable, meaning it can take any real value within a certain range and the differences between values are consistent.
A variable is any named value of a specified type that can hold any value of that type, and that can change that value at any time while the name is in scope. A constant is exactly the same as a variable except that its value must be set at the point of instantiation and the given value cannot be altered while the name remains in scope. In other words, a variable is a value that may vary while a constant is a value that always remains the same.
a variable (an unknown number/ any number).
A variable is a named storage location that can hold any data value. A variable has two associated values ; r value and l value.
