Here if this helps your welcome if not I’m sorry

So start with

2x2+3x-5=0

2x2=4

4+3x-5=0

Subtract 4 from both sides

4+3x-5=0
-4. -4

The 4 cancels out

3x-5= -4

Now add 5 to each side and the 5 will cancel

3x-5=-4
+5. +5

3x=1

Divide 3 from both sides the 3 cancels

3x=1

3/3x= 1/3

So your answer is:
x=1/3

Answer:

B. 1 + ln 2 - ln x

General Formulas and Concepts:

<u>Algebra II</u>

  • Natural logarithms ln and Euler's number e
  • Logarithmic Property [Multiplying]:                                                                     \displaystyle log(ab) = log(a) + log(b)
  • Logarithmic Property [Dividing]:                                                                         \displaystyle log(\frac{a}{b}) = log(a) - log(b)<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em />\displaystyle ln(\frac{2e}{x})<em />

<em />

<u>Step 2: Simplify</u>

  1. Expand [Logarithmic Property - Dividing]:                                                      \displaystyle ln(\frac{2e}{x}) = ln(2e) - ln(x)
  2. Expand [Logarithmic Property - Multiplying]:                                                  \displaystyle ln(\frac{2e}{x}) = ln(2) + ln(e) - ln(x)
  3. Simplify:                                                                                                             \displaystyle ln(\frac{2e}{x}) = ln(2) + 1 - ln(x)
  4. Rewrite:                                                                                                             \displaystyle ln(\frac{2e}{x}) = 1 + ln(2) - ln(x)

The table compares the number of songs and the number of videos Ruby's friends keep on their mobile phones.
Mnenie [13.5K]

A function assigns the values. The table can be represented by a function.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

No, the number of videos kept on Ruby's friends' phones cannot be expressed as a function of the number of songs. A function produces a distinct result for each input. When the input is 125, we get two distinct results. As a result, the table does not represent a function.

Hence, the table can be represented by a function.
