This question cannot be answered unless we know of a relationship between x and y.
For example if y = x+13, then , if x=100, y=113.

What function has an output value of 7 for an input value of 4?
You are basically looking for an equation with an x and y value where when 4 is set as x, y would equal 7. An equation of this is: 3 + x = y when x = 4, then y = 3 + 4 = 7
What is the value of x in the equation x y 30 when y 15?
If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
How would you work this problom If y equals 25 when X equals 5 what is the value of y when x equals 20?
There is no one solution to this problem. For example: y = x2 y = 5x y = x + 20 y = 2x / 5 + 23 These are just four of the infinite set functions that would give "y" a value of 25 when x = 5.
What is an expression for subtract 16?
Y = X - 16 X= Y + 16 X is the original value. Y is the new value of the original value - 16.
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.
How do you find precent of change?
You don't.You could find percent of change but first you would have to learn to check your spelling!Suppose the value changes from X to Ythe change is (Y - X)the proportional change is (Y - X)/X = (Y/X - 1)the percentage change is 100*(Y/X - 1)that is,100*(New Value/Old Value - 1)
How do you calculate the percent of a value against another value?
X as a percentage of Y is 100*X/Y.
What is six eighths in a percentage how did you get it?
By formula, x/y*100 = Percentage. 6/8*100 = 75% ie) The formula for percentile value is x/y *100 where X is the part of y for which percentage needs to be known, and Y is our standard. eg) What percent is is 3 of 8. 3 is our 'x' of which value needs to be known, 8, or 'Y' is our standard. 3/8*100 = 37.5%
How do you solve this problem using derivatives find two real numbers x and y so that x-y equals 100 and their product is minimized?
At first glance, this would appear to be a multivariable problem. But in actuality, with the two equations we have to work with: f(x,y) = xy x - y = 100 We can rearrange the second one to find what y is equal to in terms of x: y = 100 - x (We can also solve x in terms of y, but solving y in terms of x is conventional). then we can plug this in for y into f(x,y) to make it simply a function of x: f(x) = x(100 - x) = 100x - x2 We then take the derivative of this, setting f'(x) equal to 0: f'(x) = 0 = 100 - 2x 2x = 100 x = 100/2 = 50 This is the value of x that minimizes the product of x and y when x - y = 100. We then solve for y by plugging in the x-value into this equation: 50 - y = 100 -y = 100 - 50 y = -50 By plugging in values for which x > 50 and x < 50 into the equation f(x) = 100x - x2, we find that f(x) is indeed greater on both the intervals where x < 50 and where x > 50, proving that x = 50 is indeed an absolute minimum.
What does x - y?
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
Is x percent of y equal to y percent of x?
Let [x percent of y] = (x/100)*y. And [y percent of x] = (y/100)*x.Use the ruSo the first one (x/100)*y = y*(x /100) = y*x/100.The second one: (y/100)*x = x*(y/100) = x * y / 100, which equals y*x/100.So yes they equal the same thing, so they are equal.
What is the formula to find x value?
The formula to find the value of X would be Y-2X. This would equal to y-9 times 2 X.
How do you find percent increase and decrease?
If you start with a value x and end with a value y thenPercentage change = 100*(y/x - 1)If y > x then the above is positive and is a percentage increase andif y < x then the above is negative and is a percentage decrease.
What is the value of y when the value of x is 3?
It depends on the relationship between x and y.
In an inverse relationship how do the values of y change as the values of x increase?
Y would decrease in value as X increases in value.
What is the difference between the values of y when x equals 99 and x equals 100?
There is no way to know unless you had an equation that gives the relationship between x and y. For example, if y=2x, then when x equals 99 or x equals 100, then the value of y has a difference of 2.
What percentage is x of y and what is the formula to solve it?
To solve this, you would divide x by y, and multiply by 100.(x/y)*100 = Percent of yIE:if x=3 and y=4(3/4)*100.75*100= 75%3 is 75% of 4.
