Hope this helps out !!!!!!Do 5 A,B for 10 points.
Answer:
X = C - By over A which also is A ≠ 0
Y = C - Ax over B which is also B ≠ 0
Step-by-step explanation:
Solve for x
First subtract "By" from both sides:
Ax + By - By = C - By
Then simplify,
Ax = C - By
Divide both sides by A:
Ax / A = C/A - By/A ; A≠0
Then simplify:
X = C - By over A ; A ≠ 0.
-------------------------------------
Solve for y
First subtract "Ax" from both sides:
Ax - By - Ax = C - Ax
Simplify,
By - C = Ax
Then divide both sides by B:
By/B = C/B - Ax/B ; B ≠ 0
Simplify:
Y = C-Ax / B ; B ≠ 0.

Find the area of the polygon shown in the figure.
Answer:
16
Step-by-step explanation:
Triangle area = (1/2)*b*h
Base = b = 4
Height = h = 8
Area = (1/2) * 4 * 8 = 16
The area of the polygon shown in the figure is 16 unit square.
What is a polygon?A polygon is a closed figure made up of three or more line segments connected end to end.
Triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
The area of the triangle is defined as the product of half the base and the height of the triangle.
The area of the triangle = 1/2 x b x h
WE can see from the given figure;
The Base = b = 4
The Height = h = 8
The Area of figure = (1/2) * 4 * 8
The Area of figure = 16
Hence, the area of the polygon shown in the figure is 16 unit square.

Answer:
The error was in step 3
Step-by-step explanation:
The first two steps are correct, the property of addition of internal angles of a triangle that equal [tex]180^o[/tex] is properly used, Also the addition of supplemental angles to total [tex]180^o[/tex] is also properly used.
In step 3. there is an error. Notice how it should have been done:
[tex]\angle m+\angle n +\angle o=180^o\\\angle o + \angle p = 180^o\\then:\\\angle m+\angle n +\angle o=180^o=\angle o+\angle p\\\angle m+\angle n +\angle o=\angle o+\angle p[/tex]
Prove that the median to the hypotenuse of a right triangle is half the hypotenuse. Proof: By the Distance Formula , MN=___ Therefore OP = 1/2MN
Answer:
MN
[tex]= \sqrt{4a^2+4b^2}= 2\sqrt{a^2+b^2}[/tex]
Step-by-step explanation:
From the figure attached,
ΔMON is a right triangle and coordinates of the points M and N are M(0, 2b) and N(2a, 0).
Coordinates of midpoint P → [tex](\frac{2a+0}{2}, \frac{0+2b}{2})[/tex]
From the formula of the distance between two points,
[tex]d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
[tex]\texttt {MN} = \sqrt{(2a-0)^2+(0-2b)^2}\\\\ = \sqrt{4a^2+4b^2}\\\\ = 2\sqrt{a^2+b^2}[/tex]
Similarly, OP
[tex]= \sqrt{(0-a)^2+(0-b)^2}\\\\ = \sqrt{a^2+b^2}[/tex]
Therefore, OP
[tex]= \frac{1}{2}(MN)[/tex]
and MN

Solve for x: z(14x−2y)=7 if z equals 0 Solve for x: z(14x−2y)=7 if z does not equal 0
Answer:
[tex]z = 0[/tex]; x doesn't have a solution[tex]z\neq 0[/tex]; [tex]x = \frac{1}{14}(\frac{7}{z} + 2y)[/tex]Step-by-step explanation:
Given
[tex]z(14x -2y)=7[/tex]
Required;
Solve for x, when
[tex]z = 0[/tex][tex]z\neq 0[/tex][tex]z(14x -2y)=7[/tex]
Divide both sides by z
[tex]\frac{z(14x -2y)}{z} = \frac{7}{z}[/tex]
[tex]14x -2y = \frac{7}{z}[/tex]
Add 2y to both sides
[tex]14x -2y + 2y= \frac{7}{z} + 2y[/tex]
[tex]14x = \frac{7}{z} + 2y[/tex]
Divide both sides by 14
[tex]\frac{14x}{14} = \frac{1}{14}(\frac{7}{z} + 2y)[/tex]
[tex]x = \frac{1}{14}(\frac{7}{z} + 2y)[/tex]
The above expression is the value of x when [tex]z\neq 0[/tex]
To solve for when z = 0, we simply substitute 0 for z
[tex]x = \frac{1}{14}(\frac{7}{z} + 2y)[/tex]
[tex]x = \frac{1}{14}(\frac{7}{0} + 2y)[/tex]
0 cant't divide any number; hence, from the above expression we conclude that

i need the answer ;(
Answer:
x=100
Step-by-step explanation:
Because they are vertical angles, AEG=FEB
You can see that FED+DEB=FEB
Therefore, 80+20=FEB=100
Since FEB=100 and FEB=AEG
AEG=100
Answer:
100°
Step-by-step explanation:
In this question, vertical angles are key. If you didn't know, vertical angles are basically opposites of each other. A pair of vertical angles are equal.
ACE = 20°
FED = 80°
FED and CEG are vertical angles (+the 20 from ACE), so your answer is 100°

SOMEONE PLEASE HELP ASAP! Normal distribution models what type of variable? A.discrete random variable B.random variable C.discrete continuous variable D.random continuous variable
A normal distribution has its center at the mean and its spread is determined by the standard deviation. For the standard normal distribution, its mean is 0 and standard deviation is 1. It is in the shape of a bell curve. Most of the values fall in or around 0, forming the peak around this area. As you move away from 0, the values are less frequent which explains the drop-off. The distribution is continuous as you can have any real number (decimal or whole). It's also random because of the nature of statistics.
find the value of x
Answer:
62○
Step-by-step explanation:
To find the angle all you have to do is subtract 118○ from 180○ to get 62○. Because 180○ is a straight line! :)
Answer:
X = 62
Step-by-step explanation
To start we make x go next to 118 so they make a supplementary angle. We add x and 118 to make 180.
118 + X = 180, OR 180 - 118 = x
X = 62
In numb3rs, they use math to solve crimes. One of the ways they use Math is to reveal patterns. What is the pattern in this sequence? What would be the first and last numbers be? (6, 14, 30, 62, 126)
Step-by-step explanation:
I think the first number is 2
Then 2 x 2 = 4 so there is a difference of 4 number
Then in between 6 and 14 there is a difference of 8 so 4 x 2 = 8
Then 16 so 8 x 2 = 16
So after 126 the number is 254
If you diluted 300 mL of 8% benzocaine lotion to 5% how much could you produce
Answer:
you are diluting it 8/5 times, or 1.6 times.
You could make 230*1.6 ml of 5 percent lotion.
If you diluted 300 mL of 8% benzocaine lotion to 5%, you will be able to produce 480 ml of 5% lotion.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
The amount of benzocaine in 300 ml solution is,
Amount = 0.08 × 300 = 24ml
Since after the dilution the amount of benzocaine will be the same, therefore, we can write,
0.05 of X ml = 24 ml
X = 24/0.05
X = 480 ml
Hence, If you diluted 300 mL of 8% benzocaine lotion to 5%, you will be able to produce 480 ml of 5% lotion.

Answer:
( 3, 1650 ), Where x = 3, and y = 1650 -
Approximately
Step-by-step explanation:
Take a look at the procedure below;
[tex]y = 534x,\\y = 74.80x + 1,419\\\\y = 534x,\\y - 74.8x = 1,419\\\\( 534x ) - 74.8x = 1,419\\459.2x = 1,419\\x = ( About ) 3\\\\y = 534 * ( x ),\\y = 534 * ( 3.1 ),\\y = ( About ) 1650[/tex]
We first converted the second equation into standard form, by subtracting 74.8x on either side. Afterwards we substituted 534x in replacement of y in this second equation, and solved for x. Knowing the value of x, it was substituted back into the first equation to solve for the value of y. Hence, the resulting solution is ( 3, 1650 ) - approximately.
