3 - 6a = 9 - 6a.....subtract 9 from both sides
3 - 9 - 6a = 9 - 9 - 6a...combine like terms
- 6 - 6a = -6a ....add 6a to both sides
-6 - 6a + 6a = - 6a + 6a...combine like terms
-6 = 0...incorrect....means there is no solution to this
Answer:
A
Step-by-step explanation:
Just plug in 
.
11: 4d to the second power
12: 16y to the seventh
13: a to the second, c to the second, d to the second
14: 12a to the forth, b
15: 20 a to the third,b to the second, c to the third, d
16:6 a to the second power, b, c, d
It’s a movie? I think I heard about this movie before
Answer:
50 million
Step-by-step explanation:
You don't need to go to the trouble to find the value of k in e^(kt). Rather, you can use the given ratio directly.
When t = years after 1990, the population of 49 million took 12 years to achieve. The estimate desired is for 16 years after the year 1990. The appropriate exponential formula for the population is ...
P = 46·(49/46)^(t/12)
Then for t=16, this is ...
P = 46·(49/46)^(16/12) ≈ 50.04 . . . . million
The population in 2006 is estimated at 50 million.
_____
The form of the exponential equation we used above is ...
f(x) = (baseline value)·(ratio to baseline)^(x/(interval corresponding to ratio))
