Answer:
8) x = 12
9) x = 12
Step-by-step explanation:
Use geometric mean of legs
x=12
10)
Use geometric mean of legs
x=12
The first step for finding y is to divide both sides of the equation by 9.
9y ÷ 9 = 2x ÷ 9
When dividing 9 by 9 you must remember that any expression divided by itself equals 1.
y = 2x ÷ 9
Now write 2 ÷ 9 as a fraction.
y =
x
This means that the answer to your question is that y =x.
Let me know if you have any further questions.

The number of bacteria in species A at time t is given by: 
.
The number of bacteria in species B at time t is given by
You are asked to find N(t) which is the difference in the species at time t. Difference refers to the answer is a subtraction problem. Thus, we are asked to find N(t) = A(t)-B(t)
We subtract and obtain:
That is,
which is the last answer choice.
With respect to notation, it is common to denote an exponent using ^. So if we want to write
we can write "(.25t)^3"
