Answer:
I havent done this in a long time but I think it is 0x+4=y
Step-by-step explanation:
Solution :
= k.n (cost proportional to quantity)
35000 = k . 700
k = 
= 50
So = 50 n
Now 
(cost proportional to square of n)
3430 = 490000 P
Now, 
(fixed)
Therefore,
Total, 
Answer:
17
Step-by-step explanation:
The first thing to do is plug in the numbers for the equation. Starting with:
[-20-(-3)]/(19-20)
When you answer that you simplify the answer to
(-20+3)/(19-20)
You answer what is in the parenthesis first.
(-17)/(-1)
After this step you simplify.
17.
The answer is seventeen because any number over 1 is just the number. For example, 3/1=3. The answer is positive because the negative in the numerator and denominator cancel eachother out. leaving the answer as 17.
