What it's asking is to put the equation in either f(x) or g(x).
so for
(a) you would replace all x in f(x) equation with g(x) equation.
f(x) = 3x - 2
f(g(x)) = 3(5x + 4) - 2
solve from there
(b) g(x) = 5x + 4
g(f(x)) = 5(3x - 2) + 4
Answer:
4
Step-by-step explanation:
It depends on what you draw. So I'd like to say C, because you could pull up all the white marbles the first few draws, or none the first few and every other marble. It really depends.
We have been given an expression
. We are asked to choose the expressions, which are equivalent to our given expression.
Using exponent property
, we can rewrite our given expression as:

Upon looking at our given choices, we can see that option D is the correct choice.
Let us simplify our given expression.


Upon cancelling out
from numerator and denominator, we will get:

Using exponent property
, we will get:

Therefore, option B is a correct choice as well.
Answer: The rock would still weigh 90lbs
Step-by-step explanation:
No, weight has being proven to reduce by the further you move from the center of the Earth. But since even the tallest buildings in the world or tallest mountains are a tiny fraction of the Earth’s radius, the difference in weight won’t be something that can be measured as it’s a tiny fraction. So the mass of the rock doesn’t change what changes is the gravitational force ( g ). So the rock would still end up weighing 90lbs even at the top of the tower because it is still within the earths atmosphere.
