We can solve using y = 0 and solving for x.
81x + 18(0) = 9
81x = 9
x = 1/9
Therefore, the point (1/9, 0) sastisfies the equation.
Best of Luck!

Answer:
The monthly growth rate is 3.5%.
Step-by-step explanation:
The exponential growth function is given as follows:

Here,
<em>y</em> = final value
<em>a</em> = initial value
<em>r</em> = growth rate
<em>x</em> = time taken
The provided expression for the monthly growth of membership in the new drama club at a school is:

Comparing this function with the exponential growth function:

Then value of <em>r</em> is 0.035 or 3.5%.
Thus, the monthly growth rate is 3.5%.
