The greater-than-or-equal operator looks like a chevron (arrowhead) pointing to the right with a horizontal line of the same width beneath it.
Yes since a number and a variable and a number are a symbol.
I'm going to assume you have an equation to go with your variable? It means "Check if this number works" What to do is put the given value into the equation instead of the variable and see if the result is true - if it is you have a solution, if not you don't. I'll make one up as a demo: Equation : a + 4 = 7 is a = 2 a solution? a+4=7 2+4=7 6=7 (FALSE!) No this given value is not a solution.
substitution
The equilibrium constant of acetic acid in a solution at a given temperature is a measure of the ratio of the concentrations of the products to the concentrations of the reactants at equilibrium. It is denoted by the symbol Kc.
in this given variable in this is x.
x2 - 4x + 4 or (x - 2)2
What given?
In mathematics, a variable is a symbol that represents a quantity that can change or vary in a given problem or equation. Variables can be used to denote unknown values or to represent values that depend on other factors. They are commonly denoted by letters such as x, y, or z.
A possible value is a specific number or result that is within the range of acceptable or expected outcomes for a given variable or scenario. It represents a potential option or solution that fits the criteria being considered.
The term that is given to the variable being measured in an experiment is the dependent variable. This variable is the one that is observed and recorded based on the changes in the independent variable.
the independent variable
The term "What" is often used to represent the symbol or value that comes immediately before it in a mathematical formula or sequence. It is a placeholder that indicates a variable or unknown quantity in the context of the given formula.
