Find the value of x Kinda confused

Mathematics
1 answer:
Nat2105 [25]4 years ago
5 0

Answer:

x = 374/7

Step-by-step explanation:

all of the angles should equal to 360 degrees since it's a quadrilateral.

So,

1+ (2x+10)+(3x-5)+(2x-20) = 360

1+ 2x+10 +3x-5+2x-20 = 360

7x -14 =360

7x = 360+14

7x = 374

x= 374/7

x= 53.428...

Hope this helps!

In each figure a || b. Determine whether the third figure is a translation image of the first figure. Write yes or no. Explain y
harina [27]

Answer:

  No

Step-by-step explanation:

The second and third figures are translations of each other. The first figure appears to be a reflection of the second, not a translation. Hence the first and third figures are not translations of each other.

__

If an image is translated, all of the pre-image line segments are parallel to the image line segments. That is not the case for the first and third figures, in which the top line segments go in different directions.

Answer: She is correct because the average of the numbers 2, 3, 1, 4, 5, 2, 3, 4, 3, is 3.

Step-by-step explanation:

To find average you add all of the listed numbers, (2, 3, 1, 4, 5, 2, 3, 4, 3) which is 27. You then divide 27 by the amount of listed numbers, which is 9. 27 divided by 9 is 3. There for the average amount of strokes it takes to hit the ball into the hole of each green is 3.

Hope this helps! Please rate, it helps me know if I am explaining the answers well enough or not!! Thank you!<3

A nice, interesting question. We have to be known to a equation called as the Circle equation. It is given by the formula of:

\boxed{\mathbf{(x - a)^2 + (y - b)^2 = r^2}}

That is the circle equation with a representation of the variable "a" and variable "b" as the points for the circle's center and the variable of "r" is representing the radius of the circle.

We are told to convert the given equation expression into a typical standard format of circle equation. This will mean we can easily deduce the values of the following variables and/or the points of the circle including the radius of the circle by our standard circle equation via conversion of this expression. So, let us start by interpreting this through equation editor for mathematical expression LaTeX, for a clearer view and better understanding.

\boxed{\mathbf{Given \: \: Equation: x^2 + y^2 - 4x + 6y + 9 = 0}}

Firstly, shifting the real numbered values or the loose number, in this case it is "9", to the right hand side, since we want an actual numerical value and the radius of circle without complicating and stressing much by using quadratic equations. So:

\mathbf{x^2 - 4x + 6y + y^2 = - 9}

Group up the variables of "x" and "y" for easier simplification.

\mathbf{\Big(x^2 + 4x \Big) + \Big(y^2 + 6y \Big) = - 9}

Here comes the catch of applying logical re-squaring of variables. We have to convert the variable of "x" into a "form of square". We can do this by adding up some value on the grouped variables as separately for "x" and "y" respectively. And add the value of "4" on the right hand side as per the square conversion. So:

\mathbf{\Big(x^2 - 4x + 4 \Big) + \Big(y^2 + 6y \Big) = - 9 + 4}

We can see that; our grouped variable of "x" is exhibiting the square of expression as "(x - 2)^2" which gives up the same expression when we square "(x - 2)^2". Put this square form back into our current Expressional Equation.

\mathbf{(x - 2)^2 + \Big(y^2 + 6y \Big) = - 9 + 4}

Similarly, convert the grouped expression for the variable "y" into a square form by adding the value "9" to grouped expression of variable "y" and adding the same value on the right hand side of the Current Equation, as per the square conversion.

\mathbf{(x - 2)^2 + \Big(y^2 + 6y + 9 \Big) = - 9 + 4 + 9}

Again; We can see that; our grouped variable of "y" is exhibiting the square of expression as "(y + 3)^2" which gives up the same expression when we square "(y + 3)^2". Put this square form back into our current Expressional Equation.

\mathbf{(x - 2)^2 + (y + 3)^2 = - 9 + 13}

\mathbf{(x - 2)^2 + (y + 3)^2 = 4}

Re-configure this current Expressional Equational Variable form into the current standard format of Circle Equation. Here, "(y - b)^2" is to be shown and our currently obtained Equation does not exhibit that. So, we do just one last thing. We distribute the parentheses and apply the basics of plus and minus rules. That is, "- (- 3)" is same as "+ (3)". And "4" as per our Circle Equation can be re-written as a exponential form of "2^2"

\mathbf{(x - 2)^2 + \big(y - (- 3) \big)^2 = 2^2}

Compare this to our original standard form of Circle Equation. Here, the center points "a" and "b" are "2" and "- 3". The radius is on the right hand side, that is, "2".

\boxed{\mathbf{\underline{\therefore \quad Center \: \: (a, \: b) = (2, \: - 3); \: Radius \: \: r = 2}}}

Hope it helps.
