Answer:
1) A
2) B
Step-by-step explanation:
For this problem we use exponential growth formulas
if the population increases when t increases
If the population decreases when t increases
Where and is the population as a function of time,
is the initial population, r is the growth rate, t is the time in years.
1) In this situation we have that
, the growth is 2.4%, then
and
and the equation is:

-------- Option A)
2) In this situation we have that
, the decrease is 1.7%, then
and
and the equation is:

-------- Option B)
Idk if u got the answer or not, but It's the last graph. Just by looking at it you can point two things out.
1. The y intercept is -3 (so the graph needs to have the point (0,-3) that takes out two options.)
2. The slope is negative. (Which means the graph is going to decrease. So that takes out the other two options that have it increased.)
If they are supplements the angles add up to 180
So to find this one
180 - 37.6 = 142.4
Answer:
y=
+3
Step-by-step explanation:
1. Replace f(x) to x and replace x with y.
x=5y-15
2. Then, add 15 to both sides
x+15=5y-15+15
5y=x+15
3. Divide both sides by 5
=
+
y=
+3
4. Enjoy your answer.
