I will assume that you meant:
(x+4)/(-3x^2+12x+36) factor the denominator...
(x+4)/(-3(x^2-4x-12))
To factor a quadratic of the form ax^2+bx+c you need to find two values, j and k, which satisfy two conditions...
jk=ac=-12 and j+k=b=-4 so j and k must be 2 and -6 and the factors are then:
(x+2)(x-6) so we are now left with:
(x+4)/(-3(x+2)(x-6))
The only restriction on this function is that division by zero is undefined, so x cannot equal -2 or 6
Answer:
Step-by-step explanation:
I think option 4 is the correct answer
Answer:
$12500
Step-by-step explanation:
Given that:
Salary plan 1:
Weekly salary of $500.
And a commission of 4%.
Salary plan 2:
Straight commission of 8%.
To find:
Weekly sales for which both the plans will make the same sales?
Solution:
Let the weekly sales = $
As per question statement:
Salary as per Plan 1 = $500 + 4% of 
Salary as per Plan 2 = 8% of 
Putting both the salaries to equal to find the total weekly sales.
$500 + 4% of
= 8% of 

Therefore, the answer is:
For the sales of $12500, the salary will be same from both the plans.
All of these are mostly approximately
1) 250.3
2)3421.19
3)11494.04
4) 3.108
