Answer:
x=9
Step-by-step explanation:
We have two similar triangles because both lines are parallel, use proportions to solve:

Answer:
x can be any number lower than -29, for example 30, which will turn into -30 because of the negative symbol before x.

<em>We choose any values of x and calculate the value of y</em>

<h3>Answer: (-4, 1), (-1, 2), (2, 3).</h3>
For this case we have a function of the form:

Where,
A: initial amount
b: decrease rate
x: time in years
Substituting values we have:

For 2010 we have:
Answer:
an exponential decay function to model this situation is:
y = 1300 * (0.97) ^ x
The population in 2010 is:
y = 1083
Answer:b
