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.

Answer:

y= kx

when y = 4

x = -2

4= -2k

divide both sides by -2

k = -2

when y = 10

10 = x(-2)

10= -2x

divide both sides by -2

x = -5
