Step-by-step explanation:
Answer:
(x-10) (x+1) =0
x=10 x=-1
Step-by-step explanation:
x^2 -9x-10 =0
Factor
What two numbers multiply to -10 and add to -9
-10*1 = -10
-10+1=-9
(x-10) (x+1) =0
Using the zero product property
x-10 = 0 x+1=0
x-10+10=0+10 x+1-1=0-1
x=10 x=-1
These are the x intercepts
r=98600/30 $/day
r=9860/3
debt=1200000-98600
d=1101400
Debt=r•days
1101400=9860/3•(days)
335.1=days
336 days because you can't have a partial day and 335 days would leave $367 of debt still.
It would take the company 336 more days to earn back it's investment.
