Answer:
Step-by-step explanation:
This is function composition. We will take the g function and plug it into the f function wherever we see an x. That will look like this when it's done but before it's simplified:
and that can be simplified down to

The domain of this function will be all real numbers EXCEPT for the one(s) that cause the denominator to become undefined. Set the denominator equal to 0 and solve for x:
5x - 4 = 0 so
5x = 4 and
x = 4/5
In other words, D = {x | x ≠ 4/5}
Answer:
300,000
is bigger
Step-by-step explanation:
10 x 40 = 400
18 x 40 = 720
400 x 720 = 288,000
(area of the bedroom)
300,000
is bigger by 12,000
(so the kitchen is bigger)
4x+6 is produced each day.
So in 12 days the expression is 12(4x+6)
Solve and you get 48x+72.
