Answer:
D. The base is a positive number greater than 1
Step-by-step explanation:
The formula for exponential growth and decay is
y =a b^x
where a is the initial value
b = 1 + the growth (or decay rate)
b will be greater than 1 if we have growth and between 0 and 1 if we are decaying

Lets say billiard balls are arranged in rows to form an equilateral triangle, then the first row consists of 1 ball, second row consists of 2 balls, and third row consists of 3 balls, and so on. So there must be balls in the row.
So, the total number of balls that forms the equilateral triangle with rows is:
Let and be the total number of balls in the first and second arrangements respectively.
Then,
It has been said that there were 11 lesser balls in the second arrangement:
Since,
multiplying both the sides by 2
Therefore,
So, there were 125 balls at the set.
<h2>The solution is (x, y) = (-3, -1)</h2>
<em><u>Solution:</u></em>
<em><u>Given, system of equations are:</u></em>
-3 - x = 0 --------- eqn 1
-3y = -3 - 2x -------- eqn 2
From eqn 1,
- 3 - x = 0
<h3>x = -3</h3>
<em><u>Substitute x = -3 in eqn 2</u></em>
-3y = - 3 - 2(-3)
-3y = -3 + 6
-3y = 3
<h3>y = -1</h3>
Thus the solution is (x, y) = (-3, -1)
