1 answer:
AVprozaik [17]3 years ago
7 0

Answer:

B. 1/2

Step-by-step explanation:

y = ax^2 + bx + c

14 = a(0)^2 + b(0) + c

c = 14

10.5 = a(1)^2 + b(1) + 14

10.5 = a + b + 14 ____(i)

8 = a(2)^2 + b(2) + 14

8 = 4a + 2b + 14

4 = 2a + b + 7 ___ (ii)

i - ii

10.5 - 4 = -a + 7

6.5 = -a + 7

a = 7- 6.5

a = 0.5

the population this year is 15 I think because 60 = 100% so if you divide 60 into two you will get 30 / 50%. then divide 30 again which would be 15 and that's 25 percent.  only if you know what 60 divides by 2 and then 30 divided by 2.
