Answer:
-3
Step-by-step explanation:
The additive inverse of a number means that the sum of the number, and it's additive inverse will always be zero. The additive inverse is found by simply negating a number or making it opposite.
Therefore, 3 + x = 0, 3 - 3 + x = 0 - 3, x = -3. (x represents it's additive inverse)
Just keep in mind that finding it's additive inverse is usually the best way to do it.
Here are some ways to negate a number:
Zero subtracted by the number. (0 - n) not (n - 0).Multiplying or dividing the number by negative one. (n / -1 or n × -1)Subtracting a number by the second multiple of itself. (n - 2n) not (2n - n).________________________________

6/x + 8/x+5 = 3
What is x
Answer:
x = -7
Step-by-step explanation:
6/x + 8/x + 5 =3
5x + 14 /x =3
Step 1: Multiply both sides by x.
5x+14=3x
5x+14−3x=3x−3x(Subtract 3x from both sides)
2x+14=0
2x+14−14=0−14(Subtract 14 from both sides)
2x=−14

Let's find 1/2 - 1/6. First, write the subtraction so the fractions have denominator . Then subtract. 1/2 - 1/6 = blank/6 - 1/6 blank/blank
Answer:
1/3 or 0.3 (repeating decimal)
Step-by-step explanation:
The subtraction the fractions gives 1/3.
What is a fraction?The fractions include two parts, numerator and denominator.
Numerator: It is the upper part of the fraction, that represents the sections of the fraction.
Denominator: It is the lower or bottom part that represents the total parts in which the fraction is divided.
Given that are two fractions 1/2 and 1/6, we need to subtract them,
Firstly, equating the denominators,
1/2 = 6/12
1/6 = 2/12
Therefore,
1/2 - 1/6 = 6/12 - 2/12
= (6-2)/12
= 4/12
= 1/3
Hence on subtracting the fractions we get 1/3.

PLZ ANSWER QUICK:
The graph shows two lines, A and B:
A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 3, 0, and the ordered pair 0, 6. Another straight line labeled B joins the ordered pair 0, 0, and the ordered pair 5, 5.
Based on the graph, which statement is correct about the solution to the system of equations for lines A and B?
0, 6) is the solution to both lines A and B.
(0, 6) is the solution to line B but not to line A.
(2, 2) is the solution to both lines A and B.
(2, 2) is the solution to line A but not to line B.
Answer: Choice D
(2,2) is the solution to line A, but not to line B
==========================================================
Explanation:
Let's find the equation of line A
First we need the slope
m = (y2-y1)/(x2-x1)
m = (6-0)/(0-3)
m = 6/(-3)
m = -2
Since the point (0,6) is on line A, we know b = 6 is the y intercept.
The equation of line A is y = -2x+6.
-----------------------------
Let's find the equation for line B
So we need the slope
m = (y2-y1)/(x2-x1)
m = (5-0)/(5-0)
m = 5/5
m = 1
The y intercept is b = 0 since the line goes through (0,0)
The equation of line B is y = 5x+0 which is the same as y = 5x.
------------------------------
Our system of equations is
[tex]\begin{cases}y = -2x+6\\y = 5x\end{cases}[/tex]
We can see that plugging x = 0 into line A's equation leads to y = 6. So (0,6) is on line A. However, the point (0,6) is not on line B because plugging x = 0 leads to y = 0.
This allows us to rule out choices A and B.
--------------------------------
Let's see what happens when we plug in x = 2 to line A
y = -2x+6
y = -2*2+6
y = -4+6
y = 2
The point (2,2) is on line A
Now let's do the same for line B
y = 5x
y = 5*2
y = 10
The point (2,10) is on line B meaning that (2,2) is not on line B.
We can rule out choice C and conclude that choice D is the final answer.
Side note: Choice D should read "(2,2) is a solution" instead of "(2,2) is the solution" since there are infinitely many solutions on any given line. So another solution for example would be (0,6).

Answer:6
Step-by-step explanation:
A sociologist randomly selects single adults for different groups of three, and the random variable x is the number in the group who say that the most fun way to flirt is in person. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. x P(x) 0 0.087 1 0.344 2 0.415 3 0.154
Answer:
Yes the table shows a probability distribution
The mean is [tex]E(X) = 1.636 [/tex]
The standard deviation is [tex]\sigma = 0.845 [/tex]
Step-by-step explanation:
From the question we are told that
The data given is
x 0 1 2 3
P(x) 0.087 0.344 0.415 0.154
Generally we can evaluate [tex]P(x) * x[/tex] as
[tex]P(x) * x[/tex] 0 (1 * 0.344 ) (2 * 0.415) (3 * 0.154 )
=> [tex]P(x) * x[/tex] 0 0.344 0.830 0.462
Generally we can evaluate [tex]P(x) * x^2 [/tex] as
[tex]P(x) * x^2 [/tex] 0 [tex ](1^2 * 0.344 )[/tex] [tex ](2^2 * 0.415)[/tex] [tex ](3^2 * 0.154 )[/tex]
=> [tex]P(x) * x^2 [/tex] 0 [tex] 0.344 [/tex] [tex ]1.66 [/tex] [tex]1.386[/tex]
Generally the mean is mathematically represented as
[tex]E(X) = \sum [x* P(x)][/tex]
[tex]E(X) = 0 + 0.344+ 0.830+0.462 [/tex]
[tex]E(X) = 1.636 [/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{V(X)}[/tex]
Here [tex]V(X)[/tex] is the variance which is mathematically represented as
[tex]V(X) = [E(X^2) ]- [E(X)]^2[/tex]
Here
[tex]E(X^2) = \sum [x^2 * P(x)][/tex]
[tex]E(X) =0 +0.344+1.66+1.386 [/tex]
[tex]E(X) = 3.3900 [/tex]
So
[tex]V(X) = 3.3900 - [1.636]^2[/tex]
[tex]V(X) = 3.3900 - 2.6764[/tex]
[tex]V(X) = 0.7136[/tex]
So
[tex]\sigma = \sqrt{0.7136}[/tex]
[tex]\sigma = 0.845 [/tex]
