Trigonometry. Solving exponential equations (lacking a common base):
9^x-6=13
what is the variable?

The answer to your question is x = 7.168

Step-by-step explanation:

Equation

                               9 = 13

Process

1.- Get logarithms in both sides of the equation

                        (x - 6) log 9 = log 13

2.- Pass log 9 to the right side

                         x - 6 = log 13 / log 9

3.- Solve for x

                        x = 6 + log 13 / log 9

4.- Simplification

                        x = 6 + 1.1139 / 0.9542

                        x = 6 + 1.168

                        x = 7.168

care to share were the trapezoid shown is ?

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
