Answer:
x=-1
Step-by-step explanation:
since XY is a straight line, XM = MY
so, 5x+8=9x+12
4x=-4
x=-1
Answer:

Answer:
v(t)=(-6,000)(years)+80,000
Step-by-step explanation:
The answer is <span>8,686,308,783.</span>
To calculate this, we will use the equation for exponential function:

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:
