Question

using data from 2010 and projected to 2020, the population of the United Kingdom (y, in millions) can be approximated by the equation 10.0y-4.55x=581. where x is the number of years after 2000 what is projected population in 2026?

Answer 1

The projected population in 2026 is of 699.3 million.

Explanation:

Population:

The population, in x years after 2000, is given by the follwing equation:

`y - 4.55x = 581`

That is:

`y(x) = 4.55x + 581`

What is projected population in 2026?

2026 - 2000 = 26, so this is y(26).

`y(26) = 4.55(26) + 581 = 699.3`

The projected population in 2026 is of 699.3 million.
