What is the difference between directly propotional and inversely proportional?
In directly proportional the two variable vary in the same "direction". So, if one increases, the other increases.In inversely proportional, the two variable vary in opposite "directions". So, if one increases, the other decreases.
If y is directly proportional to x and y equals 12. What is the value of x when y equals 5?
Insufficient information. What is x when y = 12?
Is the equation y equals 2x directly proportional?
According to the equation [ y = 2x ], 'y' is directly proportional to 'x' .
Y is directly proportional to x?
If a variable (such as y) is directly proportional to another variable (such as x), they both increase and decrease simultaneously. An equation for two directly proportional variables is:y = axIt's sort of like a linear equation, but it always goes through the origin.An example is y = 6x. Notice that it forms a straight line and crosses the origin, and that y and x increase in the same direction.
What is inversely and directly proportional?
Two variables, X and Y are said to be in inversely proportional is X*Y - k where k is some non-zero constant. X and Y are said to be directly proportional if X = c*Y where c is some constant.
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.
How does y vary directly to x?
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
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.
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.
What is the difference between directly propotional and inversely proportional?
In directly proportional the two variable vary in the same "direction". So, if one increases, the other increases.In inversely proportional, the two variable vary in opposite "directions". So, if one increases, the other decreases.
