So y = (3x - 4)/2. To find the find the inverse equation, y-1,
(1) Rewrite the equation replacing all ys with xs and all xs with ys.
x = (3y - 4)/2
(2) Solve the new equation for y
x = (3y - 4)/2
2x = 3y - 4
2x + 4 = 3y
(2x + 4)/3 = y
This is your inverse equation!
y-1 = (2x + 4)/3
The equation x2 - 5x - 24 = 0 has the two solutions 8 and -3 for x.
if x = 8in the equation y=2x/(4-2) -- y=8in the equation y=2x/4-2 -- y=2it really depends on how the equation is written, because that would depend on whether you divide or subtract firsty = ( (8^2) / (4) ) - 2y = ( (64) / (4) ) -2y = 16 -2y = 14

It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
x^2 + 3x +7 = 0 doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (-3 plus or minus the square root of -19) divided by 2x = -1.5 + 2.179449471770337ix = -1.5 - 2.179449471770337iwhere i is the square root of negative 1
y = (4x+9)/(2x+3)2xy+3y = 4x+93y-9 = 4x-2xy3y-9 = x(2-2y)x = (3y-9)/(2-2y)So, inverse function is 3x minus 9 divided by 2 minus 27.
To find the inverse of a function, you replace x with y and y with x. Here, y=2x-4 would become x=2y-4. Now, we solve for y. 2y=x+4. y=(x/2)+4, and that is the inverse equation.
Since subtraction is the inverse function of addition, the additive inverse of one half is minus one half.
It is difficult to be certain. Limitations of the browser used by Answers.com means that we cannot see most symbols. Please resubmit your question spelling out the symbols as "plus", "minus", "equals". If the question is about xy = 7, then it is an equation of an inverse relationship. This is NOT the same as an inverse equation.
What is the inverse of the function f(x) = x + 12?The inverse of adding 12 is subtracting 12, so the inverse function is g(x) = x -12.(There is a special method for finding the inverse of more complicated functions, but it isn't needed here.)
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
x=x-1/x
The quadric equation is: negative b plus or minus the square root of b squared minus 4ac all over(divided by) 2a
To find the additive inverse of ANY number, add a minus sign. (If the number already has a minus sign, take the minus sign away to get the additive inverse.)
The question contains an expression but not an equation. You cannot solve an expression.
A equals Vf minus Vi divided by time equals triangle v divided by time
You can divide the whole equation by -1
