The coordinates of the point M' is (-6,2) when the point M was reflected across x =-2.
Here, assume that there is a point A(a, b). This point is reflected across the line x = -2. When reflected across this line, the value of the y coordinate of this point A will not change, only the value of the x coordinates of the point A will change.
Here, the point M(1,2) is reflected across the line x = -2.
The coordinates of the reflected point M' are (a, b).
The value of will b will remains same as that of the point M.
Now, the location of a,
the distance between the line x = -2 and a will be same as that of the distance between 2 and x =-2 which is 4 units,
So, the location of a will be fours units away from x =-2 and in the opposite direction so, a = -6
So, the Point M' is (-6,2)

Of 734 students, 442 are taking mathematics. What angle (in degrees) of a circle would show the percent of students taking mathematics? (Round your answer to the nearest whole degree.)
We need to find the angle (rounded to the nearest whole degree) of a circle that would represent the percent of students taking mathematics.
Since a complete turn around the circle has 360º, we have the following proportion:
Number of students Angle
734 360º
442 x
Then, cross multiplying the above values, we obtain:
[tex]\begin{gathered} 734x=442\cdot360\degree \\ \\ x=\frac{442\cdot360\degree}{734} \\ \\ x\cong217\degree \end{gathered}[/tex]Answer: 217º
Answer:
217°
Step-by-step explanation:
The fraction of students taking math is 442/734
we need this same fraction of the 360 degrees in a circle
442/734 * 360 = 217°

The slope intercept form equation of the line g is y = 2x + 13
Slope intercept form:
Slope intercept form the graph of a straight line and it is represented in the form of
y=mx + c
where
m represents the slope of the line
c represents the intercept of the line
Given,
Here we have the line f and g. f is parallel to g.
The equation of f is y = 2x - 5. And the line is passed through the points (-6,1).
Now, we need to find the equation of the line g.
We know that, if two lines are parallel if their slopes are equal and but they have different y-intercepts.
Based on this theory, while we looking into the equation of the line f we have easily identified that the slope of line g is also 2.
Now, we have to find the intercept,
For that, we ahve to apply the point and slope on to the standard form,
Then we get,
1 = 2(-6) + c
1 = -12 + c
c = 13
Therefore, the intercept is 13.
Then the equation of the line g is,
y = 2x +13

What is standard deviation?Data dispersion in regard to the mean is quantified by a standard deviation, or. Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high. A measure of a group of values' variance or dispersion in statistics is called the standard deviation. The values tend to be close to the set's mean when the standard deviation is low, while the values are dispersed over a larger range when the standard deviation is high. The dispersion of the data around the mean value is measured by the standard deviation. It might be helpful when comparing data sets that may have the same mean but a different range.

The expression in standard form can be written as - ( 2s² + 9s + 1 ) .
Given ; D = 1 - s^2
And given C = 3 + 3s
To find : 2D - 3C
Thus we can write it as ;
2 ( 1 - s²) - 3 (3 + 3s )
After opening the brackets we get;
2 - 2s² - 3 - 9s
Thus first we have to look for like terms as here there is a quadratic expression
we get
- 2s² - 9s -1
We can also take the minus sign common and then we will get
- ( 2s² + 9s + 1 )
Thus 2D - 3C when expressed in standard form we get - ( 2s² + 9s + 1 ) .

The sample statistic for the number of respondents who said they would vote for Brown is 0.3689, and the number of respondents who indicated they would vote for Brown is 3689.
The population in this survey are the registered voters in Raleigh. There are 10000 registered voters in Raleigh from which a sample is group selected of 450 randomly selected registered voters was conducted in which 166 said they'd vote for Brown, 257 said they'd vote for Feliz, and 27 were undecided.

5x-6=2x+9 solve and Check the solution
Answer:
x = 5
Step-by-step explanation:
Take your starting equation:
5x - 6 = 2x + 9
Your first step should be to isolate the variable, X, by having it on only one side of the equation. This can be done by subtracting one of the X values (either 5x or 2x) from either side, but I recommend the side with 2x since it's a smaller value and won't result in a negative.
(This is the right side of the equation)
2x + 9
- 2x
= 9
We need to do the same thing on the other side of the equation too, to balance both sides:
(This is the left side of the equation)
5x - 6
- 2x
= 3x - 6
This is our equation now:
3x - 6 = 9
The next step is to isolate X further by removing any constants (regular numbers) from the side with X. Since the constant on that side is -6, we need to add 6 to that side so that it's cancelled out, and do the same on the other side to balance.
(This is the left side of the equation)
3x - 6
+ 6
= 3x
And now for the other side:
(This is the right side of the equation)
9
+ 6
= 15
This is our current equation:
3x = 15
The final step is to get X completely isolated. X is being multiplied by 3, so we need to divide both sides of the equation by 3 to finally get the value of X.
(This is the left side of the equation)
3x
÷ 3
= x
And now for the other side:
(This is the right side of the equation)
15
÷ 3
= 5
Our final equation:
x = 5
We can check our answer by taking the final X value, 5, and inserting it into our beginning equation.
This is the beginning equation, as a reminder:
5x - 6 = 2x + 9
Replace all instances of X with its value, 5:
(5 · 5) - 6 = (2 · 5) + 9
After simplifying, the result is:
19 = 19, which means the X value is correct.
