Answer:

a- Slope-intercept form (y =  \frac{-7 x}{6\\} + \frac{5}{6})  ::=> 1

b- Slope of Line =  m = \frac{-7}{6}    : From Equation 1

Step-by-step explanation:

a- We have following equation:

7x + 6y = 5

Here if we re-arrange for y:

6y = 5 -7x  :: Compare it with y = mx + b

y =  \frac{-7 x}{6\\} + \frac{5}{6}

b-Compare  y = mx + b and y =  \frac{-7 x}{6\\} + \frac{5}{6}

m= -7/6 and Slope of lines parallel to the given line is shown in the equation

In a small chess tournament, 20 matches were played. Find out how many people were involved if it is known that each participant
Nina [5.8K]

Answer:

<em>5</em><em> players participated in the tournament.</em>

Step-by-step explanation:

In a small chess tournament, 20 matches were played.

Let us assume that n number of players participated in the tournament

As in each game 2 players play, so the number of ways they can play is,

=\ ^nC_2

As they played 2 games with every other participant in the tournament.

So the total number of games is,

=\ 2\times ^nC_2

But it is given to be 20, so

\Rightarrow \ 2\times ^nC_2=20

\Rightarrow \ ^nC_2=10

\Rightarrow \dfrac{n!}{2!(n-2)!}=10

\Rightarrow \dfrac{n(n-1)}{2}=10

\Rightarrow {n(n-1)=20

As 5\times 4=20, so we get n=5.

Therefore, 5 players participated in the tournament.

I would say that they equally brought the same quantity. 3/4 is 3 out of 4, 2/3 is 2 out of 3. I just see that they both made equal effort.

Is the simplified form of 2-3 + 3.3 rational?<br> Yes<br> No
N76 [4]

Answer:

YES IT IS

Step-by-step explanation:

2-3 + 3.3

= -1 + 3.3

= -4.3

We learn that:

Rational number: rational number is the number that can be written as a/b (a and b would be intergers and b is not equal to 0). Rational number would be most of numbers we use in out life, except Square root and Pi number.

In this case, -4.3 can be write as -43/10

So YES it would be a rational number

Hope this helped :3
