Answer:

a. 9

Step-by-step explanation:

Observe that 2x is the x-term with the smallest coefficient, and that x-terms are found on both sides of the equal sign. Further, observe that constants are also found on both sides of the equal sign, and the constant on the side opposite 2x is 3.

To solve this, you don't want either of those terms, 2x or 3, where they are. Subtract that sum from both sides of the equation:

3x +3 -(2x +3) = 2x +12 -(2x +3)

x = 9 . . . . . . collect terms

Which logarithmic equation is equivalent to the exponential equation below?

aleksandr82 [10.1K]

Option B: $\ln 6=5 x$ is the correct answer.

Explanation:

The exponential equation is $e^{5 x}=6$

If $f(x)=g(x)$ , then $\ln (f(x))=\ln (g(x))$

Thus, the equation becomes

$\ln \left(e^{5 x}\right)=\ln (6)$

Applying log rule, $\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)$ and thus the equation becomes

$5 x \ln (e)=\ln (6)$

Since, we know that, $\ln (e)=1$ , using this we get,

$5 x=\ln (6)$

Hence, the logarithmic equation which is equivalent to the exponential equation $e^{5 x}=6$ is $\ln 6=5 x$

Thus, Option B is the correct answer.

Simple Interest Rate Formula: $\displaystyle A = P(1 + r)^t$

<em>P</em> is principle amount
<em>r</em> is rate
<em>t</em> is time

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>P</em> = 9500

<em>r</em> = 4.5% = 0.045

<em>t</em> = 5

<u>Step 2: Find </u><em><u>A</u></em>

Substitute in variables [Simple Interest Rate Formula]: A = 9500(1 + 0.045)⁵
(Parenthesis) Add: A = 9500(1.045)⁵
Evaluate exponents: A = 9500(1.24618)
Multiply: A = 11838.7
