Answer:
<em>The population on 30th day will be </em><em>134836</em><em>.</em>
Step-by-step explanation:
This is a case of exponential growth. The general form of exponential function is,
where, a and b are constants.
The data points from the question are 
Putting the values in the function,
for 
----------1
for 
------2
Dividing equation 2 by 1,
Putting the value of b in equation 1,
Now the function becomes,
Putting x=30, we get
Answer:
See below
Step-by-step explanation:
5x + y = 9 re-arrange to y = 9-5x
use this value of 'y' in the second equation:
10x - 7(9-5x) = - 18
solve for x = 1
sub in this value of 'x' into one of the equations to compute 'y'
5 (1) + y = 9
y = 4
Answer:
2s-11
51
Step-by-step explanation:
“N fewer than Y” is Y-N, so Liza has s-11 stickers while Betty has s. They have 2s-11 stickers combined.
If Betty has 31 stickers, s = 31 and they have 2s-11 = 62-11 = 51 stickers total.
