In the direct variation 2y equals 3x what is the k value?
The question is not clear. But if you want this in the form y=kx, then k must be 1.5
Are 3x-y equals 4 and y equals 3x-4 equivalent to each other?
3x - y = 4 Get y by itself to see if it is the same as y = 3x - 4: 3x = 4 + y 3x - 4 = y Therefore, 3x - y = 4 is the equivalent of y = 3x - 4.
What is 3x y equals 4 and x y equals 0?
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2
Is y equals 2x-9 a direct variation?
11
Find the derivatives of y equals 2 sin 3x and show the solution?
y = 2 sin 3x y' = 2(sin 3x)'(3x)' y' = 2(cos 3x)(3) y' = 6 cos 3x
Is 3x plus y equals 6 a direct variation?
Yes
Is the equation 3x - 5 equals y an example of direct variation?
-2
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
How do you find the equation for a direct variation?
find the direct variation equation 3x+y=0
In the direct variation 2y equals 3x what is the k value?
The question is not clear. But if you want this in the form y=kx, then k must be 1.5
Is y equals 2x plus 5 a direct variation if so what is the constant of variation?
No, it is not a direct variation.
Does y equals 7x represent a direct variation?
y=7x
Is y equals 2x 9 a direct variation?
No.
Is y equals 24 divided by x a direct variation?
No, this is an inverse variation.
What is the constant of variation in the direct variation x-y equals 0?
1
Does the function y equals 8x represent a direct or inverse variation?
Direct
Is -3x -35y equals 14 a direct variation?
no. direct variation implies that you can simplify the problem into several forma which are equivalent to y/x = k in which k is called the constant of variation. one of these equivalent forms would by y = kx + 0 (slope intercept form) in which the y intercept must be 0 rearranging your equation gives a y- intecept of -14/35 which reduces to -2/5 since this is not zero. this is not direct variation.
