Answer:
The correct answer is c) p(x)=10x-30
Step-by-step explanation:
The answer is given in the question, you just have to replace r(x) and c(x) in the profit formula.
p(x)=r(x)-c(x)
- The revenue is: r(x)=18x
- The cost is c(x)=8x+30
p(x)=18x-(8x+30)
Solving=
p(x)=10x-30
<em>Be careful with the signs</em>
So the correct answer would be option :
c) p(x)=10x-30
Answer:
sum of the first 27 terms = -1431
Step-by-step explanation:
<h3>arithmetic series sum of the first n terms formula:</h3>
n = 27 terms
first term, a = 25
common difference, d = 19 - 25 = -6
substitute the values into the formula
Since the results are equal to each other, there is more than one solution to x
Answer:
7
Step-by-step explanation:
10x-14-12x+3=-25
-2x-14+3=-25
-2x-11=-25
take -2x to the other side
take 25 to the other side
14=2 divide
=7
