Answer:
f = 9.25 (I think but maybe I read f(4) wrong)
Step-by-step explanation:
so f(4) means x = 4.
The new equation is
f(4) = 2x4 ^2 - 4 + 9
you first do 2x4^2. The minus 4. The add 9.
the answer to that is 4f = 37
Then solve
F = 9.25
<u>x-intercepts are found by setting y=0</u>

<em>factor out a 2</em>

<em />

<em>roots should be </em>x=-1,5
therefore,
x-intercepts are (-1,0) and (5,0)
<u>
</u><u>y-intercepts are found by setting x=0</u>


therefore,
y-intercept is (0,-10)
they are the same lines
x and y are the same

i dont know for sure so bye god bless
The problem deals with a division and the rest of it, that is dividing the total amount of pencils into 9 classrooms and the rest, lets express it as fraction:
935/9 = 103 + 8/9
that is, if we multiply 103*9 we get 927 and are 8 pencils left over, therefore, 8 pencils are donated to the library and each classroom gets 103 pencils, in total 935 pencils are donated.
The estimate of the problem would be 1/4 because 6/8- 1/2 you would get 1/4.
~Good Luck!~
