1. A population of 20 rabbits is released into a wildlife region. The population is growing at a rate of 60% per year. What is the population of rabbits after 8 years and what equation did you use? 2. The population of white rhinos in 2001 was 11,670. The population is declining by 9% each year. What is the population expected to be in the year 2021 and what equation did you use?

1. 116 2. 0 or -9246

Step-by-step explanation:

1. 20 = 100%

so 20/10 = 2 meaning 2 equals 10%

now 2 x 6 (60%) = 12

12 x 8 years = 96

20 + 96 = 116

2. 11,760 = 100%

1% of 11,760 is 116.7 (11,760/100)

116.7 x 9 (9%) = 1050.3

2021 - 2001 = 20

so 1050.3 x 20 years = 21006

11,760 - 21006 = -9246

now since there cant be negative animals you could write that as 0

the answer should be a. snail

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
