First, distribute the -3(-2x + 1).
-3 x -2x = 6x -3 x 1 = -3 -3(-2x + 1) = 6x - 3
Now we have:
9 - 5 1/2x + 6x - 3
Combine like terms.
-5 1/2x + 6x = 1/2x 9 - 3 = 6
The two terms we are left with are 1/2x and 6.
The simplified version of this expression is 1/2x + 6.
Hope this helps!
It would be 6824 because 6825 would be 6830 and 6824 is the largest number that rounds down to 6820

Answer:
-36
Step-by-step explanation:
replace x with -5 and solve for the parenthesis and then take that number which would be -16 and multiply it by 9 which then would give you -144. So then you would take -144 and divide it by 4 and your answer would be -36.

Answer:
(a) f(g(x)) = g(f(x)) = x; functions are inverses
(b) f(g(x)) = g(f(x)) = x +4; functions are not inverses
Step-by-step explanation:
<h3>(a)</h3>
f(g(x)) = f(1/(6x)) = 1/(6(1/(6x))) = 1/(6/(6x)) = 1/(1/x)
f(g(x)) = x
__
g(f(x)) is the same, because f(x) = g(x).
g(f(x)) = x
- f and g are inverses of each other
__
<h3>(b)</h3>
f(g(x)) = f(x +2) = (x +2) +2
f(g(x)) = x +4
__
g(f(x)) is the same, because f(x) = g(x).
g(f(x)) = x+4
__
- f and g are not inverses of each other
