Answer:
b
Step-by-step explanation:
Step-by-step explanation:
f(x) = (x-2)/(3x+3). Let y = f(x).
Then y = (x-2)/(3x+3).
y(3x+3) = x - 2
3xy + 3y = x - 2
3xy - x = -3y - 2
x(3y-1) = -(3y+2)
x = -(3y+2)/(3y-1)
Hence, the inverse of f(x) is -(3x+2)/(3x-1).
Answer:
d
Step-by-step explanation:
add all the angles you know to get 480
the number of angles - 2 x 180 to get 720
720-480=240
divide 240 by 3 to get x
No, if we think about the lines of symmetry in a square we can see that
although all of the diagonals are lines of symmetry there are also two
that perpendicularly bisect the edges of the square, these are not
diagonals. Also If we consider a rectangle we can see that the diagonals
of a rectangle are not lines of symmetry.
