Subscription fee for a month = $ 5
Subscription fee for a writer who signs up = $ 5
Number of subscribers last month = 200
New members who joined the website = 40
Number of subscribers who left the website = 10
Hence, total subscribers in the present time = 
Now, total subscription fee received this month = 
Hence, the answer is $1150.
Answer:

Step-by-step explanation:

→ First look at the first term of each expression and see if they can be simplified, and they can

→ Now look at the a terms, since a larger one is at the top, you subtract

→ Now simplify the b and c terms


and

(f+g)(x) =

combining like terms gives you answer choice B
8x-9y=19
4x+y=-7
Multiply all terms of the 2nd by (9)===> 36x + 9y= 63
add (36x 9y= 63) to the 1st ===> 44x+0y = -44 ===> x=-1
replace x by this value in any of the equation & you'll get y=-3
