Answer: A) Exponential Function
Step-by-step explanation:
Hi, an exponential function describes best the total number of rabbits in the colony over time, because the population tends to multiply by a specific rate over time.
An exponential function can be described as a growth function, for example in the form:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form)
t= years
A = population after t years

An ordered pair (x,y) is a solution to a system of equations if it makes all the equations true.
Let's check whether (–1, 5) makes the equations true.
Plugging –1 in the first equation for x and 5 in for y, we get
–1 + 5 = 4: TRUE
Plugging –1 in the second equation for x and 5 in for y, we get
–1 – 5 = –6: TRUE
Since it makes both the equations true, it's a solution to the system of equations. So the answer choice is D, the 4th one.

Answer: 5 cakes</h3>
================================================
Explanation:
Let's start off converting the mixed number 12 & 1/4 to an improper fraction.
Do the same for the other mixed number 2 & 1/3.
-----------------------
From here, we divide the two fractions. I converted them to improper fractions to make the division process easier.
The last step is to convert that result to a mixed number.
Note that 21/4 = 5.25 and 1/4 = 0.25 to help check the answer.
-----------------------
Therefore, she can make 5 cakes. The fractional portion 1/4 is ignored since we're only considering whole cakes rather than partial ones.
