Answer:

x = -26

Step-by-step explanation:

Multiply both sides by the lowest common multiple of 4 and 3, which is 12.

3(x+2) = 4(x+8)

3x + 6 = 4x + 32 --- distribute the 4 and 3

6 = x + 32 --- subtract 3x from both sides

-26 = x --- subtract 32 from both sides

x = -26

Which of the following describes the end behavior of f(x) = 2x 3x2 − 3 ? The graph approaches 0 as x approaches infinity. The gr
Arada [10]
1) An operator is missing in your statement. Most likely the right expression is:

               2x
f(x) = -------------
           3x^2 - 3

So, I will work with it and find the result of each one of the statements given to determine their validiy.

2) Statement 1: <span>The graph approaches 0 as x approaches infinity.


Find the limit of the function as x approaches infinity:

                                    2x
Limit when x →∞ of ------------
                                 3x^2 - 3

Start by dividing numerator and denominator by x^2 =>

      2x / x^2                         2/x
--------------------------- = ---------------
  3x^2 / x^2 - 3 / x^2       3 - 3/x^2

                                      2/∞             0          0
Replace x with ∞ =>  ------------ =  ------- =  ---- = 0
                                    3 - 3/∞        3 - 0      3

Therefore the statement is TRUE.

3) Statement 2: The graph approaches 0 as x approaches negative infinity.

</span><span><span>Find the limit of the function as x approaches negative infinity:

                                        2x
Limit when x → - ∞ of ------------
                                     3x^2 - 3

Start by dividing numerator and denominator by x^2 =>

      2x / x^2                         2/x
--------------------------- = ---------------
  3x^2 / x^2 - 3 / x^2       3 - 3/x^2

                                        2/(-∞)           0            0
Replace x with - ∞ =>  ------------ =  ---------- =  ---- = 0
                                      3 - 3/(-∞)      3 - 0        3

Therefore, the statement is TRUE.</span>


4) Statement 3: The graph approaches 2/3 as x approaches infinity.

FALSE, as we already found that the graph approaches 0 when x approaches infinity.

5) Statement 4: The graph approaches –1 as x approaches negative infinity. </span>

FALSE, as we already found the graph approaches 0 when x approaches negative infinity.
