What are the restraints on this equation: ((x-3)/x^2-64)+11/x^2-64

answer:

x=11

step-by-step explanation:

step-1 : multiply the coefficient of the first term by the constant   1 • -55 = -55

step-2 : find two factors of   -55   whose sum equals the coefficient of the middle term, which is   -6 .

      -55     +     1     =     -54

      -11     +     5     =     -6     that's it

step-3 : rewrite the polynomial splitting the middle term using the two factors found in step 2 above,   -11   and   5

                    x2 - 11x + 5x - 55

step-4 : add up the first 2 terms, pulling out like factors :

                    x • (x-11)

              add up the last 2 terms, pulling out common factors :

                    5 • (x-11)

step-5 : add up the four terms of step 4 :

                    (x+5)   •   (x-11)

            which is the desired factorization

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
