Answer:
option a
step-by-step explanation:
To rationalize the expresion we need to multiply and divide the expression by the conjugate of the denominator as follows
sqrt(9) / (sqrt(3) + sqrt(x)) = sqrt(9) ((sqrt(3) - sqrt(x)) / ((sqrt(3) + sqrt(x))(sqrt(3) - sqrt(x)))
3((sqrt(3) - sqrt(x)) / (3 - x)
So the result es option a:
(3sqrt(3) - 3sqrt(x)) / (3 - x)
Let x = number of questions worth 2 and y be those worth 5.
so we have the system:-
x + y = 50
2x + 5y = 145
multiply first equation by -2:-
-2x - 2y = -100
Add this to the second equation:-
3y = 145-100
3y = 45
y = 15
and x = 50-15 = 35
Answer:- there are 35 questions worth 2 points and 15 worth 5 points.
Answer:
The price is x = $2.779
Step-by-step explanation:
From the question we are told that
The revenue is 
The cost of production is 
Generally at break even point the cost of production is equal to the revenue
So

=> 
Using the quadratic formula to solve this equation we have that
x = $2.779
