using data from 2010 and projected to 2020, the population of the United Kingdom (y, in millions) can be approximated by the equ
1 answer:
Answer:
The projected population in 2026 is of 699.3 million.
Step-by-step explanation:
Population:
The population, in x years after 2000, is given by the follwing equation:
That is:
What is projected population in 2026?
2026 - 2000 = 26, so this is y(26).
The projected population in 2026 is of 699.3 million.

Answer:
x = -3
In-Depth Steps:
1.) Start with the bottom equation:
2.) Set alone on one side of the equal sign. Your equation will look like
.
3.) Plug in for
in the first equation. You will get
.
4.) Distribute. Your equation now looks like this: .
5.) Combine like terms. You will get .
6.) Subtract 6 from both sides. You get . We can learn that Y=0.
7.) Go back to either equation and put 0 in for y.
8.) In the top equation, it would look like and the bottom equation would look like
. We basically got our answer of
, but we will plug it into the
equation, and in-fact, we get x = -3.
The value of (fg)(x)= 3x³+ x²
<h3>What is function?</h3>An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given:
f(x) = -3x+1
g(x) =
Now, (fg)(x)
=f(x) * g(x)
= (-3x+1) * ()
=-3x³+ x²
Hence, (fg)(x)= 3x³+ x²
