Answer:
<u>Ravi</u> and <u>Courtney</u>
Step-by-step explanation:
<u>Simplifying the equations</u>
<u>Penny</u>
<u>Ravi</u>
- 2x + 3y = 3
- 3y = -2x + 3
- y = -2/3x + 3
<u>Courtney</u>
- -4x - 6y = -6
- 6y = -4x + 6
- y = -2/3x + 3
<u>Edwin</u>
- 6x + 6y = 9
- 6y = -6x + 9
- y = -x + 9
<u>Ravi</u> and <u>Courtney</u> would have infinitely many solutions because they are the same equation.

The <em><u>correct answer</u></em> is:
Explanation:
An exponential function is of the form
, where a is the initial population, b is 1 plus the amount of yearly change, and x is the number of years.
For our problem, a, the initial population, is 1500.
The yearly change is 6.3%; 6.3% = 6.3/100 = 0.063. Since it is decreasing, this is negative; 1+(-0.063) = 0.937.
We use t as the number of years.
This gives us
A = pi x r^2
it gives you the diameter.
half of the diameter is the radius
therefore, A = pi x 14^2
