Answer:
20
Step-by-step explanation:
6^2 = 36 (the exponent only applies to the 6, not the entire parentheses)
(76-36) = 40
(6 - 4) = 2
40 / 2 = 20
Answer:
B: 3 is the only one that works here :)
Answer:
The domain of f(x) is x>-2, so the range of f-1(x) is y>-2
The range of f(x) is y>-1, so the domain of the f-1(x) is x>-1

Answer:
Step-by-step explanation:
-5+8x-9=3(x+3)
8x-14=3x+9
8x-3x-14=9
5x-14=9
5x=9+14
5x=23
x=23/5
----------------------
-216-3x=-12+6x
-216-3x-6x=-12
-216-9x=-12
9x=-216-(-12)
9x=-216+12
9x=-204
x=-204/9
x=-68/3
------------------
6-213-2x=-413-x
-207-2x=-413-x
-207-2x-(-x)=-413
-207-2x+x=-413
-207-x=-413
x=-207-(-413)
x=-207+413
x=206
------------------------
-(4x+9)=2x-3(2x+3)
-4x-9=2x-6x-9
-4x-9=-4x-9
Infinitely many solutions.
