You want to isolate x.  To do that, subtract 100 from both sides.  The correct result would be    x = -9.

X=-9.   because you subtract 100 from 91 to get x by itself.

Evaluate the function rule for the given value. y=15*3^x for x = -3
DENIUS [597]

Answer: y=\frac{5}{9}

Step-by-step explanation:

It is important to remember that an Exponential function has the following form:

f(x) =a* b^x

Where  “b”  is b > 0 and b \neq 1 , "a" is a coefficient, "x" is the Independent variable and f(x) is the Dependent variable.

In this case, you have the following Exponential Function given in the exercise:

y=15*3^x

If the value of Dependent variable is -3, then:

x=-3

So, you must substitute that value of "x" into the function:

y=15*3^{(-3)}

And now you must evaluate:

1. According the Negative exponent rule:

a^{-n}=\frac{1}{a^n}

Then:

y=\frac{15}{3^{3}}

2. Simplifying, you get:

y=\frac{15}{27}\\\\y=\frac{5}{9}
