1) what is y+xy if x = 6 and y = 3


2) what is (p-r)^2 if p = 4 and r = 1

Answer:

[tex]x=-3[/tex]

Step-by-step explanation:

[tex]9-2x=15[/tex]

Subtract 9 from both sides:

[tex]9-2x-9=15-9[/tex]

[tex]-2x=6[/tex]

Divide both sides by -2:

[tex]\frac{-2x}{-2}=\frac{6}{-2}[/tex]

[tex]x=-3[/tex]

Answer:

5

Step-by-step explanation:

The expected value is −390(0.9976) + (150,000 − 390)( 1 − 0.9976) = −$30

-$30. This was the right answer on Brainly.

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:

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:

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:

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

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

1000 g boxes costs £10.50

Cost of 200g in 1000g box = 10.50/5 = 2.10

200 g box costs £2.50

Hope this will help....

Answer: 1000g Bird Food gives the better value for money because when you muliply 2.5- pounds times 5 you get 12.50 pounds for 1000g but not in the case for 1000g for 10.50 pounds

Step-by-step explanation:

200g Bird Food - 2.50 pounds

1000g Bird Food - 10.50 pounds

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:

Option 1

Step-by-step explanation:

look at the graph in bot cases y still positive in the upper part of the graph

only x moves from the right side to left side of the graph

Take one point A (2,2) to A'(-2,2)

from 2 to -2 (x-4=2-4=-2)

from 2 to 2 ( y still the same)

Answer:

Es racionalS

Answer:

It would be NEGATIVE because a positive number times a negative number, the answer is negative.

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:

D.6 calls

Step-by-step explanation:

To find the average first we need to add up all the numbers

7+1+4+10+7+4+9=42

Next we would divide 42 by the number of days which is 7 days
