What is the solution to the system of equations?

nata0808 [166]

Answer:

I am sorry thats a lot to type out.

Step-by-step explanation:

I will say that to know if its rational, you have to see if the integer can be written in a fraction (like 0.333, 89/10, -4, 0)

Truth statement are statements or assertions that is true regardless of whether the constituent premises are true or false. See below for the definition of Euclidean Postulates.

<h3>What are the Euclidean Postulates?</h3>

The five Euclidean Postulates are;

1. Any two points can be joined by a straight line segment.

2. In a straight line, any straight line segment can be stretched indefinitely.

3. A circle can be formed using any straight line segment as the radius and one endpoint as the center.

4. Right angles are all the same.

5. If two lines meet a third in a way that the sum of the inner angles on one side is smaller than two Right Angles, the two lines will inevitably collide on that side if they are stretched far enough.

The truth statements relating to the attached pictures and their equivalent Euclidean Axiom are;

a) The right angle in the first page of the book shown and the right angles in the last page of the book shown are all the same. (Postulate 4);

b) If the string from the Yoyo dangling from hand in the picture is rotated for 360° such that the length of the string remains equal all thought, and the point from where is is attached remains fixed, it will trace a circular trajectory. (Postulate 3)

c) The swords held by the fighters can be extended into infinity because they are straight lines (Postulate 5)

There are only blue cubes, yellow cubes and green cubes in a bag.

Rama09 [41]

Let the yellow cubes be x

yellow = x
blue = 2x // Blue cubes is twice of yellow
Green = 8x // Green is four times of blue

Ratio:
Yellow : Blue : Green
1 : 2 : 8

P(Yellow) = 1/11

-----------------------------------------------------------------------------
Answer: The probability of getting a yellow cube is 1/11.

Solve the system by substitution.<br> -6y = x<br> x +y = -30

Komok [63]

Answer:

$- 6y = x \\ \\ y = - \frac{x}{6} \\ \\ \\ x + y = - 30 \\ x + ( - \frac{x}{6} ) = - 30 \\ \\ x - \frac{x}{6} = - 30 \\ \\ \frac{6x}{6} - \frac{x}{6} = - 30 \\ \\ \frac{6x - x}{6} = - 30 \\ \\ \frac{5x}{6} = - 30 \\ \\ 5x = - 30 \times (6) \\ \\ 5x = - 180 \\ \\ x = - \frac{180}{5} \\ \\ x = - 36 \\ \\ \\ \\ y = - \frac{x}{6} \\ \\ y = - \frac{( - 36)}{6} \\ \\ y = \frac{36}{6} = 6 \\ \\ y = 6 \\ \\ ( - 36 \: , \: 6)$
