The factors of the expression is 2and -3
A=34.547237
b=2.547237
determined by trial and error with a calculator
From A-->B in a 2:3 ratio means that it's 2/(2+3) of the way up AB
So 2/5 of the x of AB = 2/5×(18-2) = 2/5 (16)
= 32/5 = 6 2/5 + the original x of A (2) = 8 2/5
2/5 of the y of AB = 2/5×(12-6) = 2/5 (6)
= 12/5 = 2 2/5 + the original y of A (6) = 8 2/5
Therefore the answer is:
(8 2/5, 8 2/5)
A. in 11 years it will be reduced to 858.99, in 10 it will be reduced to 1,073.
b. 43 years
