Answer:

C

Step-by-step explanation:

Using the rules of logarithms

loga + logb = log(ab)

loga - logb = log(\frac{a}{b} )

logx^{n} ⇔ nlogx

Given

4lnx + ln3 - lnx

= 3lnx + ln3

= lnx³ + ln3

= ln(x³ × 3)

= ln(3x³) → C

Romashka-Z-Leto [24]

Answer:

A

Step-by-step explanation:

Area of a triangle = \frac{bh}{2}

where b = base length and h = height

the triangle shown has a base length of 2 and 1/2 and a height 4. and 2/5

So area =

\frac{2\frac{1}{2} *4\frac{2}{5} }{2} \\\\2\frac{1}{2} *4\frac{2}{5} =11\\\\\frac{11}{2} =5.5

5.5 also = 5\frac{1}{2}

Hence, the correct answer is A

Solve for x.
cluponka [151]

The correct answer is none of the ones listed. The correct answer is 18/5.

In order to find this, follow the order of operations.

−(−2−5x)+(−2)=18 ---> Distribute the negative

2 + 5x - 2 = 18 ----> Combine like terms

5x = 18 -----> Divide by 5

x = 18/5

Aloiza [94]

Answer:

y =x-12

Step-by-step explanation:

(x_1, y_1) = (16, 4) \ \ \ and \ \ \ (x_2, y_2) = (17, 5)

Equation of straight line is

y-y_1 =\frac{y_2-y_1}{x_2-x_1}  (x-x_1)

y-4 =\frac{5-4}{17-16}  (x-16)

y =(x-16)+4

y =x-12
