PLS HELP ME! I GOT THE ANSWER I JUST NEED TO SHOW THE WORK.
Solve for X.
Answer: 6
Answer: x = 6
=================================================
Work Shown:
According to the remote interior angle theorem, we can add the interior angles to get the exterior angle that is not adjacent to the interior angles.
So we'll add interior angles D = 6x+8 and E = 5x+8, and that sum leads to 82.
Let's solve for x
(6x+8)+(5x+8) = 82
11x+16 = 82
11x = 82-16 ....... subtracting 16 from both sides
11x = 66
x = 66/11 ...... dividing both sides by 11
x = 6
-----------------
A slightly longer method involves letting y be the missing interior angle of triangle DEC.
Then we can say D+E+C = (6x+8)+(5x+8)+y = 180. This is because the interior angles of any triangle always add to 180.
Furthermore, we also know y+82 = 180, since the angles y and 82 are a linear pair. Solving for y leads to y = 180-82 = 98
Plug this back into the first equation and solve for x
(6x+8)+(5x+8)+y = 180
(6x+8)+(5x+8)+98 = 180
(6x+8)+(5x+8)= 180-98
(6x+8)+(5x+8) = 82 .... note how this equation shows up again
The steps to solving are shown in the previous section.

Calculate the area of a circle with the radius of 2cm. Pie=3
Answer:
12
Step-by-step explanation:
The formula to find the area of a circle is:
[tex]\pi[/tex][tex]r^{2}[/tex]
Where "r" is the radius of the circle.
In this case, the radius is 2, and as per what is given in this problem (what the problem asks one to use), pi is rounded down to 3.
The equation will be:
3 * 2^2
Simplify, remember the order of operations:
3 * 4
12
Answer:
12.56 cm
Step-by-step explanation:
Area of a circle is A=3.14 r to the second power.
so the radius is 2 cm. I would do 2 x 2 and that equals ,4 next 4 x 3.14= 12.56
i don't know what pie=3 means but this is my answer from the best of my ability.

Please help. The picture below explains the problem.
Answer:
If the line is gonna be perpendicular then the slope going to be the inverse opposite. therefore the slope of our new line will be 1/4
Now to find the y intercept follow these steps:
y=mx+b
y=1/4x+b
3=1/4(4)+b
3=1+b
b=2
Now that we have the y intercept (b) and the slope (m) we can make our equation.
y=1/4x+2
Step-by-step explanation:
Identify the interval(s) on which the function y = -x2 + 5x + 14 is positive.
A.) X < -2 and x > 7
B.) X > 2 and x < -7
C.) -7 < x < 2
D.) -2 < x < 7
Given:
[tex]y=-x^2+5x+14[/tex]
To find:
The interval on which the given function is positive.
Solution:
We have,
[tex]y=-x^2+5x+14[/tex]
Splitting the middle term, we get
[tex]y=-x^2+7x-2x+14[/tex]
[tex]y=-x(x-7)-2(x-7)[/tex]
[tex]y=(x-7)(-x-2)[/tex]
[tex]y=-(x-7)(x+2)[/tex]
Using zero product property, we get
[tex]x-7=0\text{ and }x+2=0[/tex]
[tex]x=7\text{ and }x=-2[/tex]
-2 and 7 divide the number line is three interval.
Interval Signs of [tex]y=-(x-7)(x+2)[/tex] Result
(-∞,-2) (-)(-)(-) Negative
(-2,7) (-)(-)(+) Positive
(7,∞) (-)(+)(+) Negative
So, the function is positive for the interval (-2,7), i.e., -2 < x < 7.
Therefore, the correct option is D.

What is an equation of the line that passes through the point (-5,2) and is parallel
to the line 4x - 5y = 5?
Answer:
Step-by-step explanation:
first change the equation so it just equals y
-5y = 5 -4x
y = 4/5x -1
since this new equation has to be parallel to the previous line, the slopes are the same
y = 4/5x + b
now we have to make sure the new equation passes through (-5,2) so we plug in -5 for x and 2 for y
2 = 4/5(-5) + b
2 = -4 + b
b = 6
so the final equation is
y = 4/5x +6
The equation of the line that passes through the point (-5,2) and is parallel to the line 4x - 5y = 5 is 5y - 4x = 30
The equation of a line in point-slope form is expressed as:
[tex]y-y_0=m(x-x_0)[/tex]
m is the slope of the line
(x0, y0) is any point on the line
Given the equation 4x - 5y = 5.
Rewrite in standard form:
-5y = -4x + 5
y = 4/5 x - 1
The slope of the line passing through the given equation is 4/5
Substitute the slope and the point into the equation:
[tex]y-2=4/5(x+5)\\5(y-2)=4(x+5)\\5y-10=4x+20\\5y-4x=20+10\\5y-4x=30[/tex]
Hence the equation of the line that passes through the point (-5,2) and is parallel to the line 4x - 5y = 5 is 5y - 4x = 30

Water flows down the Mississippi river at about 1.2 miles per hour. The relationship between hours and miles the water has traveled is... Discrete or continuous
Answer:
Continuous
Step-by-step explanation:
Given
[tex]Rate = 1.2\ miles/hour[/tex]
Required
Determine if this relationship is discrete or continuous
Numbers in their whole form (i.e. 1,2,3.....) represent discrete values while others with decimals (such as 0.2,0.9, 1.2...) represent continuous values
From the above analysis, we can see that 1.2 fall in the category of continuous values.
Hence, the relationship between both parameters is continuous

if you have 30 N force going left and a 10 N force going right, what is the force
Answer:
20 N
Step-by-step explanation:
Since, both the forces are acting in opposite directions.
Therefore,
[tex]Net \: Force = 30 \: N - 10 \: N \\ \\ = 20 \: N [/tex]
Answer:
20N
Step-by-step explanation:If you take the direction that the 30N force is acting in as positive, then since the 10N force acts in the opposite direction, the Net (resultant) force on the object is 20N. If the numbers were flipped, it would be -20N.
