Answer:
9x^2 -24x +13
Step-by-step explanation:
(g º f)(x) = g(f(x))
g(f(x)) = (3x-4)^2 - 3
(3x-4)^2 = 9x^2 - 24x + 16
g(f(x)) = 9x^2 - 24x + 16 - 3
g(f(x)) = 9x^2 -24x +13
Answer:
Step-by-step explanation:
So we know that there are 213 oranges and Theresa fills each bag with 3 oranges, so we can represent each bag as 3x. She keeps filling until she reaches 51 oranges.
First. let's write this as an equation, She is starting with 213 oranges and filling x bags with 3 oranges to the point she has less than 51 oranges.
213 - 3x < 51
Now add 3x to both sides,
213 - 3x + 3x < 51 + 3x
213 < 51 + 3x
Now we subtract 51 from both sides,
213 - 51 < 51 - 51 + 3x
162 < 3x
Now we divide both sides by 3,
162/3 < 3x/3
We find the answer,
54 < x
x > 54 bags
