( -2, 1 ) is the image of ( -1,2 ) reflected across the line y=-x.
What you must do in this case is to find the roots of the polynomial.
We have then:
x ^ 2 + 20x + 100 = 36
Rewriting:
x ^ 2 + 20x + 64 = 0
The values of the roots are:
x1 = -4
x2 = -16
Remember that the values of the roots are what make the polinome zero
Answer:
x1 = -4
x2 = -16
Answer:
9 years = .000000706$
Step-by-step explanation:
convert 7% to decimal 0 .07
17,500 x .07 = 1,225
1 year 1,225
2 year 85.75
3 year 6.0
4 year .42
5 year .029
6 year .002
7 year .000144
8 year .000010088
9 years = .000000706$
Since the exchange rate of euro to USD right now is 1:1.11, therefore he spent 150x1.11=166.5 USD. Therefore, he has 250-166.5=83.5 USD left(assuming the exchange rate is the same, 1.17).
