How do you solve word problems using variables?
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
What is literal equations?
A literal equation is an equation where variables represent known values. Literal equations allow us to represent things such as distance, time and interest as variables in the equation.. Using variables instead of words is a 'time saver'. For example d=rt. Meaning distance = rate and time
What does pi actually represent?
Generally, Pi is used to represent the rate of change of the circumference of a circle as it's diameter increases. This can be shown using the equation [circumference = Pi * diameter], that is the circumference of a circle is always Pi times larger than it's diameter.
How do you solve for x using a quadratic equation?
For an equation of the form ax² + bx + c = 0 you can find the values of x that will satisfy the equation using the quadratic equation: x = [-b ± √(b² - 4ac)]/2a
What is 9x2 equals 10x plus 2?
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
How do we use variables in the real wold?
Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.

What ıs capacitance?
Capacitance is resistance (not ohms) to a change in voltage using stored charge. The differential equation of a capacitor is dv/dt = i/c. This means that the rate of change of voltage is directly proportional to current and inversely proportional to capacitance.

In order to represent a type of relationship a third table is created using the keys from the two entities being related?
That is done in a many to many relationship.
What should you do when using diatomic elements in an equation?
When using diatomic elements (such as O₂, N₂, H₂, etc.) in an equation, remember to write them with a subscript of 2 to represent that they exist as molecules in their natural state. This is important for balancing chemical equations accurately.
What is the chemical equation CH3?
The chemical formula CH3 does not represent a valid chemical equation. Chemical equations are representations of chemical reactions using chemical formulas and symbols.
An expression in which symbols and formulae represent a chemical reaction?
A chemical equation is an expression in which symbols and formulae represent a chemical reaction. It shows the reactants on the left side and the products on the right side, with coefficients to balance the number of atoms on each side.
Explain how you know that y must decrease when x decreases?
First you have to tell me what equation you are using as the basis of this relationship between x and y.
When both dimensions of a figure are changed using the same scale factor is the change proportional or non proportional?
If it is a 2-dimensional figure then it is proportional.
What is a decimal that does not show a repeating pattern called?
These numbers, such as pi, are known as trancendentalnumbers, because they represent a value that is not the solution of an algebraic equation or a quotient using real numbers.
What is the speed equation for waves?
The speed of a wave can be calculated using the equation: speed (v) = frequency (f) x wavelength (λ). This equation demonstrates the relationship between the speed, frequency, and wavelength of a wave.
