Answer:
A
Step-by-step explanation:
The rule is, whenever you plug in g(x) into f(x) or vice versa, they always must equal x. So if you plugged in g(x) into f(x), then the outcome should be <em>x</em>. If the output is not x, then they are not inverses.
Answer:
4z^2+7z
you have to combine the like terms
7z+4z^2+6-6
then becomes
(4z^2) + (7z) + (6-6)
gets you to the simplified version which is
4z^2 +7z
It would be 7500 because if you divide 75000/10 your answer would be 7500
Answer:
84
Step-by-step explanation:
Plug in 9 for k.
5(9)(2) - 6
first: (9)(2) = 9 x 2 = 18
5(18) - 6
second: 5(18) = 5 x 18 = 90
last: 90 - 6 = ?

Answer:
There are 8 more girls
Step-by-step explanation:
If you divide 32 by 8 (since the ratio is 3:5 which is 8 parts (3+5)). You get 4.
Thus, there are 12 boys and 20 because 3*4 is 12 and 5*4 is 20. 12+20 is 32.
