6^{x+8}=17^{2x-2}\ \ \ \ \ \ |both\ sides\ log_6\\\\log_66^{x+8}=log_617^{2x-2}\\\\x+8=(2x-2)log_617\\\\x+8=2xlog_617-2log_617\\\\x-2xlog_617=-2log_617-8\\\\x(1-2log_617)=-2log_617-8\ \ \ \ |divide\ both\ sides\ by\ (1-2log_617)\\\\x=\frac{-2log_617-8}{1-2log_617}\\\\x=\frac{-(log_617^2+8)}{-(log_617^2-1)}\\\\x=\frac{log_6289+8}{log_6289-1}

Answer:

C = 125

Step-by-step explanation:

Since a straight line is 180 degrees. We can conclude that:

10x + 15 + 5x = 180

And that:

C = 10x + 15

First we need to find the value of x to find C. So,

10x + 15 + 5x = 180

15x + 15 = 180

       - 15    -15

15x         = 165

15x/15     = 165/15

x              = 11

So now, we need to substitute the values of x into C and solve it.

C = 10(11) + 15

   =  110 + 15

   = 125

What are the y-intercept and the horizontal asymptote of g(x) = 3x + 4?
Stells [14]

The coefficient of the variable will be the horizontal  asymptote . Hence the horizontal  asymptote will be 3

<h3>How to calculate the y-intercept and horizontal asympototes</h3>

Given the function g(x) = 3x + 4

The y-intercept is the point where x = 0

g(0) = 3(0) + 4
g(0) = 0 + 4
g(0) = 4

Hence the y-intercept is at (0, 4)

For the horizontal  asymptote of g(x) = 3x + 4

The coefficiet of the variable will be the horizontal  asymptote . Hence the horizontal  asymptote will be 3
