Identify the error in the student solution shown below. Find the correct answer.
AlexFokin [52]

Answer:

Step-by-step explanation:

The answer is Since 0 in ln(3x) - 0 is not a logarithm, the property of logarithms cannot be used here.

The difference shown cannot be written as a quotient of logarithms.

The step ln(x2) = ln(3x) - (0) reduces to

ln(x2) = ln(3x).

The possible solutions are 0 and 3, with 0 being extraneous.

The symmetry of a hyperbola with a center at (h, k) only occurs at y = k. True or False
Vikki [24]
A hyperbola with a center at (0, 0) can be defined  as x²/a² − y²/b² = ±1.<span> 
</span>The statement "<span>The symmetry of a hyperbola with a center at (h, k) only occurs at y = k" </span>is false, because a hyperbola have many different orientations.
It doesn't have to be symmetric about the lines y = k or x = h.

Solve the rational equation x divided by 6 equals x squared divided by quantity x minus 1 end quantity, and check for extraneous
pychu [463]

Answer:

x = 0 and x = \textrm{negative one fifth}

Step-by-step explanation:

Given:

The rational equation to solve is given as:

\frac{x}{6}=\frac{x^2}{x-1}&#10;

We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,

x\times (x-1)=6\times x^2\\x^2-x=6x^2\\\textrm{Bringing all variables to the right side, we get:}\\6x^2-x^2+x=0\\5x^2+x=0\\x(5x+1)=0\\x=0\ or\ 5x+1=0\\x=0\ or\ x=-\frac{1}{5}&#10;

Now, for x=0, the rational equation is equal to 0. So, x=0 is a solution.

Also, x=-\frac{1}{5} is also a solution as the equation's denominator is defined at that point.

So, no extraneous solution.
