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.
2x to the fourth power minus 162 equals -146
x = 4 and y = 7
g(x) = x/2
If: 9-2x = 35 then x = -13
x = 4 and y = 7 which will satisfy both equations
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.
An equation where x equals 3.
It seems to be some kind of simultaneous equation with too many equality signs in it.
What is additive inverse
I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
if y = 2x then x = log2 y
The [ 2x + 1 ] represents a function of 'y' .
The multiplicative inverse of 3+2x is 1/(3+2x).
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
If Y equals 2X - 2X - 24, then there is one root, and it is -24. The two 2X's cancel each other out.
3x2 + 2x - 8 = 0 is a quadratic equation.
If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.
