Answer:

A=0.25

B=0.35

C=1.05

Step-by-step explanation:

1. A+B=0.6

2. A+C=1.3

3. C=3B

2 subtract 1:

  • C-B=0.7

3 substituted:

  • 3B-B=0.7
  • B=0.35
  • C=0.7+0.35=1.05
  • A=0.6-0.35=0.25

Adriano runs a website that helps writers write better stories. Every month, Adriano receives a subscription fee of $5 from each
tatuchka [14]
There aren't really any instructions for this, so I'll just go ahead and find the total amount of money for both months. The first month Adriano had 200 subscribers. 5 times 200 is 1000, so Adriano received $1000 that month. The second month 40 members joined, but 10 cancelled their subscription. Taking this into account, we'll just say that 30 members joined. 30 times 5 is 150, and 150 plus 1000 is 1150. Therefore, Adriano had to have received $1150 the second month.

I'm not entirely sure what the question was to begin with, but I hope this answers it!

Create a quadratic polynomial function f(x) and a linear binomial in the form (x − a).
erik [133]
Quadratic polynomial  x^2 - x - 6 = f(x)
binomial  (x-3)

dividing:-
                x   + 2
          ----------------------
x - 3   )  x^2  - x   -  6
             x^2 - 3x
             ----------
                     2x - 6
                     2x - 6
                     --------
                      .........

result of division is (x + 2)  
s o we can write the function as (x - 3)(x + 2)

Part 2  f(a)  = f(3)   =  (3)^2 - 3 - 6 = 0

Part3  The remainder Theorem  states that  the remainder when a polynomial is divided by (x - a)  then the remainder is f(a).  If f(a) = 0 then  x - a is a factor.
In the above case f(3) = 0 therefore (x - 3) is a factor of our polynomial.
