Answer:
28.25 million
Step-by-step explanation:
Population of the country:
- in 2001 - x million
- in 2006 - 30.4 million
Population of the country as percent:
- in 2001 - 100%
- in 2006 - 100% + 7.6% = 107.6%
Write a proportion:
Cross multiply:
Divide by 107.6:
The data isn't proportional because there is a y-intercept.
20/1 is not equal to 28/2, which isnt equal to 36/3 and so on
Answer:
(x+12)
Step-by-step explanation:
The middle number is 8 and the last number is -48.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 8
Multiply together to get -48
Can you think of the two numbers?
Try -4 and 12:
-4+12 = 8
-4*12 = -48
Fill in the blanks in
(x+_)(x+_)
with -4 and 12 to get...
(x-4)(x+12)
But, since (x-4) isn't an option, the answer would be (x+12)
