Which of the following is true regarding the solutions to the logarithmic equation below?

Note that the logarithmic function is determined for all

Now solve the equation:

Since this is an extraneous solution.

Since this is true solution.

correct option is D

Hence, option D is correct.

x=9 is a true solution and x=-9 is a extraneous solution.

Step-by-step explanation:

" In mathematics, an extraneous solution (or spurious solution) is a solution, such as that to an equation, that emerges from the process of solving the problem but is not a valid solution to the problem "

" A true solution is a valid solution of the equation "

We are given a equation as:

Now as we know that the logarithmic function is not defined for negative 'x'.

Hence x= -9 is a invalid solution or we can say is a extraneous solution.

and x=9 is a true solution.

Hence, option D is correct.

x=9 is a true solution and x=-9 is a extraneous solution.

i think the length is 12 and the width is 17

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
