What is the linear equation used to represent a proportion?
y = cx where c is the constant of proportionality.
Does x equals 5y - 5 vary directly with x?
0
What is direct variation equation?
y = kx, where k is a constant, and x and y are the two variables.
Can a variable be a constant?
In algebra variables express a relationship within an equation and these are often used to give meaningful expressions to represent practical situations. These relationships often require a constant to be included in order to balance the equation turning the relationship from one of proportionality to one of equality. The variables themselves are only constant for a given set of conditions. i.e The voltage across a resistance of 60 ohms carrying a current of 4 amps will be 240v. (V= current x resistance). A separate constant is not needed in this case as the resistance is defined by the other two properties. In science one example of a constant that is thought to be variable is the speed of light, which for all practical purposes is considered to be constant but is thought to have changed gradually with time. I don't know what possible ways there are of verifying this.
How do you find the constant and slope for direct variation equations?
For a direct variation equation the constant MUST be 0. Then the ratio of a pair of values of the two variables is the slope.
How do you find constant of proportionality using equation?
If the equation is y = kx then the constant of proportionality is k.
What is the equation for y varies directly as the cube of x?
y = c*x3 where c is the constant of proportionality.
How can you identify a unit rate or constant of proportionality in a table In a graph In an equation?
In a table, divide a number in one column by the corresponding number in the other column. In a graph it is the gradient of the line. The equation, for the variables X and Y will be of the form Y = mX and the constant of proportionality is m.
What is the constant of proportionality in the equation y 2.5x?
answer: 2.5 :)
The volume of a given mass of an ideal gas at constant pressure is?
directly proportional to the Kelvin temperature
Are constant variables and derived variables the same?
Constant variables are constant, they do not change. Derived variables are not constant. They are determined by the other values in the equation.
How does e equals mc2 relate energyAND MASS?
The equation states that energy is directly proportional to mass and that the constant of proportionality is equal to the square of the velocity of light (in vacuum).
What is the linear equation used to represent a proportion?
y = cx where c is the constant of proportionality.
What is an equation that shows that one variable varies directly with the square of the other variable?
y=x^2 * k k=constant of proportionality OR y/x^2 = k
Which is an equation of a direct proportion?
y = kx where k is a non-zero constant is an equation of direct proportionality between x and y.
What is the constant of proportionality of the linear function?
The linear function has the form y=mx+b, which I expect you have heard of. The 'b' is the y-intercept, and the 'm' is the slope. A constant of proportionality is something you have with direct variation, which is where the line goes through (0,0). This happens when 'b' equals zero. So now the equation is just y=mx, and the constant of proportionality is 'm'.
What is the the constant of proportionality for the distance y traveled in miles in x hours as represented by the equation y divided by x?
It is the speed, which must be maintained at a constant value.
