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 degree of a polynomial is the highest power that appears in the polynomial. For more than one variable, you must add the powers for each variable, for example, a3b2 is of degree 3 + 2 = 5.
The independent variable
the independent variable
How about that when given a quadratic equation what would you use to determine whether or not it has any solutions.
You would solve for M1, which represents the molarity of the stock solution. The equation M1V1 = M2V2 is used to calculate the molarity of a stock solution when you know the volume and molarity of a more diluted solution.
Yes, a polynomial time verifier can efficiently determine the validity of a given solution in a computational problem.
You cannot. You can determine the third variable if two are given but not determine two when given only one. You have to find some other way to first determine volume or density.
The variable under investigation is typically referred to as the "dependent variable" in a research study. This is the variable that is being measured or observed to determine how it is affected by changes in another variable, known as the independent variable.
Dependent variable: Whether children were given to adopted parents or natural parents. Independent variable: social relationships at ages 8 and 16.
A dye that changes color depending on whether it's exposed to an acid or alkaline solution is called a pH indicator. pH indicators are commonly used in chemistry labs to determine the acidity or alkalinity of a solution based on the color change they undergo.
To determine the variable cost in a business scenario when given the fixed cost, you can subtract the fixed cost from the total cost. Variable costs are expenses that change based on the level of production or sales, while fixed costs remain constant regardless of production levels. By subtracting the fixed cost from the total cost, you can isolate the variable cost component.
To determine the volume in liters from the given molarity of a solution, you can use the formula: volume (in liters) amount of solute (in moles) / molarity (in mol/L). This formula helps calculate the volume of the solution based on the concentration of the solute in moles per liter.
substitution
If Variable cost and sales ratio is provided then by using mathematical equation approach mixing figures can be found by using provided figures. Sales = Variable cost + Sales percentage of (Variable cost)
in this given variable in this is x.
Without an equality sign the expression given can't be considered to be an equation and therefore has no solution
