Answer:
(a) 3 - 2x - 2x² (b) -21
Step-by-step explanation:
given, y +2x² = 3 -2x
make y the subject:
y = 3 - 2x - 2x²
if y = f(x)
then
f(x) = 3 - 2x - 2x²
(b)<u> to find f(3) we need to replace x with 3:</u>
<u />
3 - 2(3) - 2*(3)²
-21

When using fractions and whole numbers turn the whole numbers into fractions like ---> 3/1
and if their like 3 5/6 (for example) you would multiply the denominator by the whole number ---> 3*6=18 then add what's on the numerator with it. so 18+5=23 which would make it 23/6
Just some tips for making it easier!

We want to know how many brownmies did Fred and his family eat together.
We will call to the total of the brownies by 1. On this case, after Fred ate 1/3 of the brownies, he will have:
This means that he has left 2/3 of the brownies. After his family ate 1/6 of the brownies:
This means they will have left 1/2 of the tray of brownies, and that they ate half of it.
Its 47/8 hope this helped all you need to do is keep the 8 like how it is and then you do 5 times 8 and add 7 thats it
