Answer:
Step-by-step explanation:
A.
R(x)=px=x(-45 x+1800)=-45 x²+1800 x
B.
C(x)=7000+100 x
C.
P(x)=R(x)-C(x)=-45 x²+1800 x-(7000+100 x)
or P(x)=-45x²+1800 x-100 x-7000
or P(x)=-45 x²+1700 x-7000
wait wait wait I feel like I did this before but I don't at the same time-
I have no brain too so yeah sorry- :((
This question is very odd with the arrangement.
(6z2 - 4z + 1)(8 - 3z)
The rule is number always has to be put first not the alphabets.
If you did not mention 2 as number 2 but the other character, it is okey but if it is not, it should be rearranged.
P(x) = amount made - cost
p(x) = 20x-7x-10
p(x) = 13x -10
