One estimate of the population of the world on January 1, 2005, is 6,486,915,022. The population is estimated to be increasing a

luda_lava [24]

The answer is <span>8,686,308,783.</span>

To calculate this, we will use the equation for exponential function:
$y=x(r+1) ^{n}$
y - the future population
x - the current population
r - the rate of increasing the population
n - the number of years

It is given:
x = 6,486,915,022
r = 1.4% = 0.014
n = 2026 - 2005 = 21

Therefore:
$y= x(r+1)^{n} =6,486,915,022*(0.014+1) ^{21} = 8,686,308,783$

Find the solution to the system of

Sav [38]

Answer:

(0, 3).

Step-by-step explanation:

y = 2x + 3

y = -3x + 3

2x + 3 = -3x + 3

5x = 0

x = 0

y = 2 * 0 + 3

y = 0 + 3

y = 3

y = -3 * 0 + 3

y = 0 + 3

y = 3

So, the solution to the system of equations is (0, 3).

Hope this helps!
