Hello, I know that this site constantly recieves an extreme amount of questions and I think it is great for indvidiuals to help each other. That being said, I do have one math question that I am stuck on, but I understand if it dosen't get reviewed. I appreciate the help anyways, thanks. :)
Heres my question:
A small company borrows money and remains in debt to its lenders for a period of time. The functionf(x)=−4x2+10x+60f(x)=−4x2+10x+60 represents the amount of debt the company has, in thousands of dollars, x years after opening its business.
Approximately how many years after opening its business will the company be out of debt?
4.7 years
5.3 years
5.8 years
6.4 years
+36915 5.3 years
If this represents their debt when it equals zero, they are out of debt:
0 = -4x^2 +10x +60 solve for 'x' using the quadratic formula a=-4 b=10 c=60
x = 5.3 yrs
