Find the inverse of f x 3x plus 9?
f(x) = 3x + 9 y = 3x + 9 so 3x = y - 9 x = y/3 - 3 Therefore, the inverse function is g(x) = x/3 - 3
What is the inverse of 3x plus 2?
y = 3x + 2 y-2 = 3x x = (y-2)/3 So the inverse is (x-2)/3
What does y equals 3x plus y and y equals x-9 equal?
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
What is the inverse of y equals 3x plus 8?
y = 3x + 8Replace x with y and y with x.x = 3y + 8Solve for y.x - 8 = 3y3y = x - 8y = (x-8)/3
What is the inverse of 2x-8?
y = x² - 2x - 8 Swap x and y to find the inverse: x = y² - 2y - 8 Now get y by itself: y² - 2y = x + 8 (Complete the square): y² - 2y + 1 = x + 9 (y - 1)² = x + 9 y - 1 = ±√(x + 9) y = 1 ±√(x + 9) Then there are two functions: f(x) = 1 - √(x + 9) and f(x) = 1 + √(x + 9) but an inverse can only be one function. The functions above are a mirror image of the original function, but it is not an inverse (graph these functions). There is no inverse. Everything above is completely wrong. This is the inverse: (x+8)/2 I don't know where the x² came from in the first answer, but to work out the question as asked: if y=2x-8 y+8 = 2x (y+8)/2 = x so, as the above answer stated, (x+8)/2 is the answer.
Find the inverse of f x 3x plus 9?
f(x) = 3x + 9 y = 3x + 9 so 3x = y - 9 x = y/3 - 3 Therefore, the inverse function is g(x) = x/3 - 3
Is f of x equals negative 9 subtract x divded by 3 a inverse function?

What is the inverse of 3x plus 2?
y = 3x + 2 y-2 = 3x x = (y-2)/3 So the inverse is (x-2)/3
What is the inverse function of y equals 3x-3?

3x minus y equals 9 solve for y?
3x-y=9 y=3x-9
What is the inverse function of y3x-1?

What is the inverse function of y -2 3x plus 2?
If you mean: y-2 = 3x+2 then as a straight line equation it is y = 3x+4
Factor 9x squared minus 6xy plus y squared minus 81?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
How do you get y by itself in the equation 3x-6y equals 9?
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
How do you solve for y 3x-y equals 12?
-9
What does y equals 3x plus y and y equals x-9 equal?
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
How do you factor 9xx-6xy yy-81?
(3x - y + 9)(3x - y - 9)
