Is y -3x a direct variation?
Yes, the equation ( y = -3x ) represents a direct variation. In a direct variation, the relationship between two variables can be expressed in the form ( y = kx ), where ( k ) is a constant. Here, the constant ( k ) is -3, indicating that ( y ) varies directly with ( x ) but in the opposite direction.
Is the problem y equals 3x a direct variation if so what is the constant of variation?
y=3x is a direct variation in that y varies directly with x by a factor of 3. Any linear equation (a polynomial of degree 1, which is a polynomial equation with a highest exponent of 1), is a direct variation of y to x by some constant, and this constant is simply the coefficient of the "x" term. Other examples: y=(1/2)x is a direct variation, and the constant of variation is 1/2 y=-9x is a direct variation, and the constant of variation is -9
Find a equation of variation where y varies directly as x and y equals 0.8 when x equals 0.4?
direct variation: y = kx y = kx k = y/x = 0.8/0.4 = 2
Is 2x plus 3y equals 0 a direct variation?
Direct variation refers to two variable quantities have a constant (unchanged) ratio, in which a variable "varies directly with the other."In order to have a direct variation, the constant of variation must be not equal to 0 in the equation y=kx, where k is the constant.When you try to put 2x+3y=0 into that formula (y= form), you get:2x+3y=03y=-2x ;Subtract the 2xy=(-2/3)x ;Divide by 3Your constant of variation is -2/3, and since it is less than 0, it is does variate directly. Therefore, y varies directly as x.
What kind of cost is direct Labor?
Direct labor is direct cost as it varies with variation in production level and directly related with number of units of product.

How would you go about solving this direct variation question and what is the answer- If P varies directly as the square of Q and the constant of variation is 6 what is the value of P when Q equals 12?
If P varies directly with the square of Q then the equation would be in the form of P = kQ2, where k is the constant of variation so the new equation would be: P = 6Q2, so when Q = 12 we have P=6*122, or P = 864
Find an equation of variation where y varies directly as x One pair of values is y equals 80 when x equals 40?

Direct labor is direct cost as it varies with variation in production level and directly related with number of units of product.
How are direct variation and joint variation related?
Both are variations of certain kinds of equations. X=kY is a direct variation since X varies directly as Y and k is the constant of variation. X=k/Y is an inverse variation where X varies inversly as Y and k is the constant of variation. Both of these variations are also functions.
When x is 2.25 y is 6.75 y varies directly with x write the direct variation equation in the form y kx. direct variation equation find y when x is 4.2. when x 4.2 y?
y = 3x because when x is 2.25 y is 6.75 a ratio of 1 to 3 and so when x is 4.2 y is 12.6
What is a direct square variation?
