3 - 24 + 8 + 42

= (3 - 24) + 8 + 42

= (-21 + 8) + 42

= -13 + 42

= 29

Answer: 15 players.

Step-by-step explanation:

number of games played in the tournament = 105 games

nunber of games played by each player against another = 1 game each.

Solution:

Number if player who participated in the tournament.

if each player played a game against every other player, and they were 105 games played at the tournament.

n ( n – 1 ) /n = m

= n ( n – 1 ) 2 = 105

open the bracket

n^2 – n = 210

n^2 – n – 210 = 0

( n – 15 ) ( n + 14 ) = 0

n = 15

15 players Participated In the tournament.

Answer:

The information with which the parabola is constructed is insufficient

Step-by-step explanation:

The vertex form of a quadratic equation is given as follows;

f(x) = a(x - h)² + k

The steps to draw the graph of a quadratic function given in vertex form, we are required to do the following;

1) Definition of the variables, (a, h and k) of the quadratic equation (given in vertex form)

The vertex of the quadratic equation in vertex form is (h, k)

2) Given that the vertex point is given, the vertex point is then plotted on the graph

3) Draw the parabola axis of symmetry that passes through the vertex point

4) Determine the direction to which the parabola opens from the sign of the variable a as follows;

i) When a is positive, the parabola opens upwards

ii) When a is negative, the parabola opens downwards

5) Determine if the parabola has x-intercepts and plot them

A parabola has x intercepts when;

i) The parabola opens downwards, that is, the variable, a, is negative and also the vertex (h, k) is above the x-axis or k is positive

ii) The parabola opens upwards, that is, the variable, a, is positive and also the vertex (h, k) is below the x-axis or k is negative

6)  Determine y-intercepts and plot them as follows;

At the y-intercept, x = 0, therefore;

f(x) = a(x - h)² + k

f(0) = a(0 - h)² + k = a·h² + k

6) If any additional points are required, they should plotted and then the graph of the function is then drawn making sure to be symmetrical about the vertex and to pass through all the plotted points.

Answer:

When p2 – 4p is subtracted from p2 + p – 6, the result is:

p2+p-6-(p2-4p)=p2+p-6-p2+4p=5p-6

To get p – 9, subtract from this result x:

5p-6-x=p-9

Solving for x:

5p-6-x+x-p+9=p-9+x-p+9

4p+3=x

x=4p+3

Answer:

1) When p2 – 4p is subtracted from p2 + p – 6, the result is 5p-6

2) To get p – 9, subtract from this result 4p+3

Answer:

x=8.625

Step-by-step explanation:

ok so the lines mean absolute value so its actuall positive soyou get 3+8x+8=80

so add 3 and 8 to get 11+8x=80

subtract 11 to get 8x=69

then divide it by 8 so x is by itself

x=8.625 hope this helped :)

Answer:

x = 3 , x = -3

Step-by-step explanation:

3 | -8x | + 8 = 80

3 | -8x | = 72

Solve the negative and positive case:

Negative-

-3 ( -8x ) = 72

24x = 72

x = 3

Positive-

3 (-8x ) = 72

-24 = 72

-x = 3

x = -3

Answer:

Es racionalS

tep-by-step explanation:

Es racional, ya que se puede expresar de la siguiente fracción: 123/1000 , recordar la regla de que por cada número después de la coma se le agrega un 0 al denominador.

Answer:

0.123 is a rational number

Step-by-step explanation:

0.123 is the ratio of 123 to 1,000 so it's rational

Answer: 1/2

Step-by-step explanation:

Total options  = 8

Number of A's = 4.

Probability  = desired outcomes / total outcomes

= 4/8

You can simplify 4/8 to :

Answer: It already tells you what DE= 60

Step-by-step explanation:

Since F is the midpoint of DE that means DF=FE

So create equation [tex]2x+6+2x+6=4x+12[/tex]

When DF and FE is added your answer should equal DE

So you write the equation [tex]4x+12=2x+36[/tex] to find x and once x is found substitute your answer for x

[tex]4x+12(-12)=2x+36(-12)[/tex] subtract 12 on both sides 36-12= 24

[tex]4x=2x+24[/tex] subtract 2x on both sides 4x-2x=2x

[tex]2x=24[/tex] divide 2 into both sides 24/2=12 x=12

[tex]4(12)+12=2(12)+36[/tex]  

4x12=48+12=60   2x12=24+36=60

Answer:

Step-by-step explanation:

(x+2)/2 = 1

x + 2 = 2

x = 0

Hey there! I'm happy to help!

AREA

To find the area of a parallelogram, you multiply the base by the height.

12(6)=72

The area is 72 square centimeters.

PERIMETER

The two diagonal sides are 8 cm and the two bases are 12 cm.

8+8+12+12=40

The perimeter is 40 cm.

Have a wonderful day! :D

Answer:

X=6+2=8 * 6= 48

Step-by-step explanation:

If you divide 48 by 6 you get 8  then you - 2 and you get six. so x =6

Answer:

Length: 120cm, Width: 72cm

Step-by-step explanation:

Let x = length

Let 3x/5 = width

2x+2(3x/5)=384

2x+(6x/5)=384

16x/5=384

16x=1920

x=120cm

Substitute 120 for x in width

360/5 = width

width = 72cm

Answer:

A ) -4/3

how to calculate slope-

(Y2 - Y1) / (X2 - X1)

Answer:

A

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, 3) and (x₂, y₂ ) = (3, - 9) ← 2 points on the line

m = [tex]\frac{-9-3}{3+6}[/tex] = [tex]\frac{-12}{9}[/tex] = - [tex]\frac{4}{3}[/tex] → A
