1. -21
2. −39
3.−42
4. -5
5. −3
for the other question u can use calculator :)
Answer:
y= 1-x
Step-by-step explanation:
● (a^2x)/a^(x-y) = a
This means that:
● 2x-(x-y) = 1
● 2x - x +y = 1
● x + y = 1
Substract x from both sides
● x+y -x = 1-x
● y = 1-x
To get better at 12's:
Write down on your paper your 1's facts in column skip 5 and 11 going to 14 (a vertical line - line that goes up and down). To the right of that column, write your two's facts 0 to 8 and repeat again. Then you will have your 12's! Should look as follows
12's:
0 0 = 12 x0
1 2 = 12 x1
2 4 = 12 x2
3 6 = 12 x3
4 8 = 12 x4
6 0 = 12 x5
7 2 = 12 x6
8 4 = 12 x7
9 6 = 12 x8
10 8 = 12 x9
12 0 = 12 x10
13 2 = 12 x 11
14 4 = 12 x 12
Yes, I agree with the researcher's method. All the values of 
in the table correspond to the values of n by using their formula.
Step-by-step explanation:
Step 1:
If we substitute the values of n in the researcher's equation and we get the right values of , we can agree with the researcher's method.
The researcher's formula is 
Here is the wombat population and n is the number of years.
Step 2:
When n = 1, 
when n = 2, 
when n = 3, 
when n = 4, 
when n = 5, 
As all the values correspond to the values on the table, I agree with the researcher's method.
