Hello!
To find the transformation from T to T^-1, you need to convert the negative symbol to a positive symbol, and the positive symbol to the negative symbol.
Therefore, the answer is T^-1 : ( x + 7, y - 2).
Your ultimate goal is to get the variable secluded all by itself. You'll have to use the opposite operation to do this and remember, what you do to one side, you have to do to the other.
1. 9s + 3 = 57
2. Subtract 3 from each side. This will result in 9s = 54
3. To undo the multiplication of 9s you'll divide both sides by 9. 9s/9 = 54/9
4. The ending result is: s=6
5. Go back and check your work by substituting it in your original equation.
Answer:
18
Step-by-step explanation:
xy + 4 = 40
xy = 40 - 4
xy = 36
What two numbers can b multiplied to give 36? Then add them.
9 + 4 = 13
18 + 2 = 20
6 + 6 = 12
12 + 3 = 15
The odd option is 18
Answer:
Population of the city after 7 years from now, P(7) = 6370
Given:
Initial Population, 
rate, r(t) = 1200 /yr
S(t) = [/tex]\frac{1}{1 + t}[/tex]
Step-by-step explanation:
Let the initial population be 
The population after T years is given by the equation:
(1)
Thus, the population after 7 years from now is given by using eqn (1):
