Example: 2/3 y = x this simple example means this: you are to find the fraction that multiplies to it and equal one. (of course, just flip it around) then move THAT behind x. It vary directly if it is the same as this - y=kx Tip: subtraction and addition automatically says "no , this does not vary directly
What else can I help you with?
Does x vary directly to y?
The answer depends on x and y. They are not defined for this question.
Y equals 12x do x and y vary directly?
X and Y are directly propotinal.If one is varing other is varing too.
Does y vary directly as x in y equals 8x?
Yes. Directly and 8 times as fast.
The variables x and y vary directly when x equals -5 and y equals 21 what is the constant of variation?
y = kx k = y/x = 21/-5 = - 21/5
Does y vary directly as x in this function y8x?
The expression "y8x" seems to be unclear or potentially a typographical error. If you meant to express a relationship such as ( y = kx ) (where ( k ) is a constant), then yes, ( y ) would vary directly as ( x ). This means that as ( x ) increases or decreases, ( y ) changes proportionally. Please clarify if you meant something else!
Does x vary directly to y?
The answer depends on x and y. They are not defined for this question.
Does y vary directly as x in this function y equals x plus 2?
No.
Y equals 12x do x and y vary directly?
X and Y are directly propotinal.If one is varing other is varing too.
Does y vary directly as x in y equals 8x?
Yes. Directly and 8 times as fast.
What does it mean for x and y to vary directly?
That means that if "x" varies by a certain factor, "y" will vary by the same factor. For example, if "x" is double, then "y" will also double.
The variables x and y vary directly when x equals -5 and y equals 21 what is the constant of variation?
y = kx k = y/x = 21/-5 = - 21/5
If y varies directly as x and y 18 when x 24 find x when y 15?
If y varies directly as x and y is 18 when x is 24, then y is always three fourths of x. So if y is 15, then x is 20.
If y varies directly as x and y 36 x 9 then what is the value of x when y 12?
If y varies directly as x and y is 36 when x is 9, then y is always four times the value of x. So if y is 12, then x is 3.
If y varies directly as x squared find k when x 2 and y 8?
If y varies directly as x and if x = 2 when y = 8 then k = 4.
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.
Is y4x a direct variation?
To determine if ( y = kx ) represents a direct variation, ( y ) must vary directly as ( x ) with a constant ratio ( k ). The expression ( y = 4x ) indicates that ( y ) is directly proportional to ( x ) with a constant of variation ( k = 4 ). Thus, yes, ( y = 4x ) is indeed a direct variation.
What is the constant of variation k if x .5 and y 1 Assume y varies directly as x?
If y varies directly as x then k = 2.
