Step-by-step explanation:
This question doesn’t make sense?..
The value of b is 
Explanation:
The given quadratic equation is 
And has x - intercept 
To determine the value of b, let us substitute the coordinates
in the given quadratic equation 
Substituting the x - intercept in the equation
, we have,

Simplifying, we have,


Adding the constant terms, we get,

Subtracting both sides by 10, we have,

Dividing both sides by -2, we get,

Hence, the value of b is 
Answer:
After 15 years the use of said machine is no longer profitable
Step-by-step explanation:
it should be used, as long as the money generated is not smaller as the costs generated. By setting both formulas equal (calculating the x value for when they are equal) you get x = 15 and x = -2.5(which doesnt make sense in this context).
