y/x is a constant; so first of you can solve for this constant. y/x=6/-3, or y/x=-2
y/4=-2
y=-8

F varies jointly as g h and j One set of values is f equals 18 g equals 4 h equals 3 and j equals 5 Find f when g equals 5 h equals 12 and j equals 3?
f = 54
Suppose y varies inversely with X use the information to find K and choose the equation of variation. X equals 7 and y equals 3?
xy = K so K = 21
When f varies jointly as a and t and inversely as the square of b what is the answer when determining f when k equals 3 a equals 4 t equals 6 and b equals 2?
I am assuming that k is the constant of proportionality so that f = k*a*t/b2 = 3*4*6/22 = 18

How do you find the answer to this equation: 3n equals 18
If an equation of variation where y varies directly as x and y equals 15 when x equals 5 find when x equals 19?
y = 3x y = 3*19 = 57
If y varies directly as x and y equals 18 when x equals 3?
y varies directly as x y=kx, where k is a constant y=18 when x=3 18=3k k=6 y=6x
If y varies directly as x and y equals fifteend and when x equals three find y when x equals twelve?
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
If w varies directly as 2x-1 and w equals 9 when x equals 2 find x when w equals 15?
The phrase "varies directly as" means that there is a number k such that w = k(2x - 1). From the results given for w = 9 when x = 2, 9 = k(4 - 1), or k = 3. Then when w is 15, 15 = 3(2x - 1), or 15 = 6x - 3, or 6x = 15 + 3, or x = 18/6 = 3.

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.
When f varies jointly as a and t and inversely as the square of b what is the answer when determining f when k equals 3 a equals 4 t equals 6 and b equals 2?
I am assuming that k is the constant of proportionality so that f = k*a*t/b2 = 3*4*6/22 = 18
