Solve for x :

4 - (2x + 4) = 5

1) x = -10

2) x = 5/2

3) x = 1/2

4) x = 6

<h3><u>Answer</u><u>:</u><u> </u></h3>

➛ 4 - 2x + 4 = 5

➛ 2x + 4 - 4 = 5

➛ 2x + 0 = 5

➛ 2x = 5

➛ x = 5/2

Thus, The value of x is <u>5/2</u><u>.</u><u> </u>

If g(x)=3x-2, find g(8)-g(-5)

Brut [27]

<h2>Answer:</h2> $g(8)-g(-5)=39$

<h2>Explanations:</h2>

Given the function

$g(x)=3x-2$

Get g(8) by substituting x = 8 into the function;

$\begin{gathered} g(8)=3(8)-2 \\ g(8)=24-2 \\ g(8)=22 \end{gathered}$

Get g(-5) by substituting x = -5 into the function

$\begin{gathered} g(-5)=3(-5)-2 \\ g(-5)=-15-2 \\ g(-5)=-17 \end{gathered}$

Take the difference in the result to have;

$\begin{gathered} g(8)-g(-5) \\ =22-\mleft(-17\mright) \\ =22+17 \\ =39 \end{gathered}$

Hence the difference between the given functions is 39

Answer:

<em>Probability ≈ 0.3571</em>

Step-by-step explanation:

Consider the steps below;

$Total Number of Outcomes - 9C4,\\9 ! / 4 ! * ( 9 - 4 ),\\9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / 4 * 3 * 2 * 1 * 5 * 4 * 3 * 2 * 1,\\\\Total Outcomes = 126,\\\\Number of Outcomes - 3C2 * ( 6C2 ),\\3C2 = 3,\\6C2 = 15,\\\\Number of Outcomes = 3 * 15 = 45,\\\\Probability; 45 / 126 = ( About ) 0.3571$
