x=(y-3)/2
do you mean y = 2x + 8 ? the inverse is y = (x - 8)/2
x10 = x5.x5 = (x5)2 [x power five whole squared] Equation is x10 + x5 - 2 Replacing x10 (x5)2+x5 - 2 Substituting x5 by Y Equation becomes Y2 + Y - 2 = 0 Y2 + 2Y - Y - 2 = 0 Y(Y + 2) - 1(Y+2) = 0 (Y-1)(Y+2) = 0 The values of Y are 1 and -2 Y = x5 = 1 Therefore, x = 1 Y = x5 = -2 x = fifth root of -2, which is an imaginary value.
The solution to the equation 2x plus 2 is 2(x + 1).
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
x^5+2x^4+4x^2+2x-3
y=2x+4 --> x=2y+4 ==> y=(x-4)/2
x=(y-3)/2
This is an unclear equation, actually some sort of addition. (Opposite means negative? Inverse?) 2x + x + (-x) + (-1) = 7 + 2 (-x) ?? 2x - 1 = 7 - 2x 4x = 8 x = 2
-x(x2 - 2)(x2 + 3)
y = f(x) = (2x + 1)/(x - 1)y*(x - 1) = (2x + 1) xy - y = 2x + 1xy - 2x = y + 1x(y - 2) = y + 1so x = (y + 1)/(y - 2) assuming y�2.So the inverse function is f-1(x) = (x + 1)/(x - 2)
do you mean y = 2x + 8 ? the inverse is y = (x - 8)/2
x^2 + 3x - 2; -x^2 - 3x + 2andx - 1; 1 - x
x10 = x5.x5 = (x5)2 [x power five whole squared] Equation is x10 + x5 - 2 Replacing x10 (x5)2+x5 - 2 Substituting x5 by Y Equation becomes Y2 + Y - 2 = 0 Y2 + 2Y - Y - 2 = 0 Y(Y + 2) - 1(Y+2) = 0 (Y-1)(Y+2) = 0 The values of Y are 1 and -2 Y = x5 = 1 Therefore, x = 1 Y = x5 = -2 x = fifth root of -2, which is an imaginary value.
g(x) = x/2
I would say that functions have inverses, rather than equations.One simple way to find the inverse of a function is to switch the x and y:The inverse of y = (3x+5)/2 is . . . x = (3y+5)/2.You can take this inverse and solve it for y: (2)x=(2)(3y+5)/2 2x=3y+5 3y+5=2x 3y=2x-5 y=(2x-5)/3.Notice that in the original you multiply by 3, add 5, and divide by 2. On the inverse, you multiply by 2, subtract 5, and divide by 3. You do the inverse operations in the reverse order.
