</h3>
First of all cross multiply
We have
<h3>
</h3>
Next divide both sides by 9x to make sure that w stands alone
That's.

Answer:
For this case we know that at the starting year 2000 the population was 9 billion and we also know that increasing with a double time of 20 years so we can set up the following model:
And if we solve for b we got:
And then the model would be:
Where y is on billions and t the time in years since 2000.
And for this equation is possible to find the population any year after 2000

The answer to this question would be: 300; 20; 150; 10
When you multiply 15 x 32, you can divide both numbers into this:
15= 10 + 5
32= 30 +2
Then the multiplication becomes (10+5) * (30+2) which will result in 4 partial product like this:
10*30= 300
10* 2= 20
5* 30= 150
5* 2= 10
You have to substitute 25 for b to simplify the expression.
53(25) -7(25) -6(25) +1
=1325 - 175 - 150 +1
=1001
The answer is D because to find the slope of a line that is perpendicular to another, you have to find the opposite reciprocal. so here the slope would be -1/4. now, take that slope and put it into an equation. like the following:
now to find b you must insert the points into the equation (plug in 4 for x, and 15 for y).
b then equals 16. so, the answer is D.
