Answer:
Alright so on this type of problem you just perform the operation they ask for, which in this case is subtraction.
Your first step will be to set up the problem:
f(x) - g(x)
Next you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8
Hope this helped!

Answer:
-3
Step-by-step explanation:
-11b + 7 = 40
Subtract both sides by 7.
-11b = 33
Divide both sides by -11.
b = -3

Answer:
R (Q) = 100Q - 4Q^2 , MR = 100 - 8Q , MR at Q (10) = 20
Step-by-step explanation:
Demand curve ie Price as a function of Quantity ; P (Q) = 100 - 4Q
R, total revenue from sale = Q . P (Q)
R (Q) = (100 - 4Q) Q
MR is addition to total revenue due to per unit change in sale, = d R / d Q
d ( 100Q - 4Q^2 ) / d Q
MR at quantity , 10 unit of sales = 100 - 8 (10)
MR at Q (10) = 20
0.35*1430=500.5, anywhere up from 1,430 pounds will equate to over 500$
