Answer:
1) A
2) B
Step-by-step explanation:
For this problem we use exponential growth formulas
if the population increases when t increases
If the population decreases when t increases
Where and is the population as a function of time,
is the initial population, r is the growth rate, t is the time in years.
1) In this situation we have that
, the growth is 2.4%, then
and
and the equation is:

-------- Option A)
2) In this situation we have that
, the decrease is 1.7%, then
and
and the equation is:

-------- Option B)
Answer:
x + 6y + 30 = 0
Step-by-step explanation:
x + 6y = 12
6y = -x + 12
y = -⅙x + 2
Slope: -⅙
y - (-4) = -⅙(x - (-6))
y + 4 = -⅙(x + 6)
-6y - 24 = x + 6
x + 6y + 30 = 0

Answer:
-45
Step-by-step explanation:
8 - 8 / 2 + 7^2
PEMDAS Parenthesis Exponents Multiplication Division Addition Subtraction
Exponents 7^2 = 49
8 - 8 / 2 + 49
Division 8 / 2 = 4
8 - 4 + 49
Addition 4 + 49 = 53
8 - 53
Subtraction 8 - 53 = -45
-45
