Write ln 2x + 2x ln x -ln 3y as a single logarithm.
andreev551 [17]

Answer: option c.

Step-by-step explanation:

 To solve this problem you must keep on mind the properties of logarithms:

ln(b)-ln(a)=ln(\frac{b}{a})\\\\ln(b)+ln(a)=ln(ba)\\\\a*ln(b)=ln(b)^a

Therefore, knowing the properties, you can write the expression gven in the problem as shown below:

ln2x+2lnx-ln3y=ln2x+lnx^2-ln3y\\\\=ln(2x)(x^2)-ln3y\\\\=ln(\frac{2x^3}{3y})

Therefore, the answer is the option c.

What is the slope of the graph of 2x – 6y = 9?
notsponge [240]
Let's make our equation in the form of y = mx + b

<span> 2x – 6y = 9

Add 6y on both sides

2x = 6y + 9

Subtract 9 on both sides

6y = 2x - 9

Divide 6 on both sides

y = 1/3 - 3/2

Now, we have it in the form of y = mx + b

In y = mx + b, m is the slope and b is the y-intercept

That means in y = 1/3 - 3/2, the slope is A) 1/3.

Your answer is A) 1/3</span>
