What does it mean when it says determine whether the given value of the variable is a solution?
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.
What else can I help you with?
What reduces an equation that has two variables to an equation that has one variable. It is then possible to find the solution for this variable.?
substitution
How do you determine the degrees of a given polynomial?
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.
What name is given to the variable you plot on the x-axis?
The independent variable
What name is given to the variable we plot on the x- axis?
the independent variable
What is the most challenging mathematics question in junior secondary?
How about that when given a quadratic equation what would you use to determine whether or not it has any solutions.
For which variable do you solve to determine the molarity of the stock solution given the equation M1V1 equals M2V2?
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.
Can a polynomial time verifier efficiently determine the validity of a given solution in a computational problem?
Yes, a polynomial time verifier can efficiently determine the validity of a given solution in a computational problem.
How do you find the volume and density if only the mass was given?
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.
What is the name given for the variable under investigation?
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.
What were the DV of hodges and tizard?
Dependent variable: Whether children were given to adopted parents or natural parents. Independent variable: social relationships at ages 8 and 16.
What is the name given to a dye that changes colour depending on whether it's an acid or alkaline?
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.
How can one determine the variable cost when given the fixed cost in a business scenario?
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.
How can one determine the volume in liters from the given molarity of a solution?
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.
What reduces an equation that has two variables to an equation that has one variable. It is then possible to find the solution for this variable.?
substitution
How can you determine sales when variable cost is given and sale ratio?
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)
What is the given variable to -132x-3 12x-4?
in this given variable in this is x.
How do you check whether -11 is a solution of 6 t - 4?
Without an equality sign the expression given can't be considered to be an equation and therefore has no solution
