2x - y = -3
-2x - 8y = 12​

Answers

Answer:

x= -2 y= -1

Step-by-step explanation:

stack the 2 equations on top of each other and add them together

the 2x and -2x cancel out and you are left with -9y=9

this gives you y= -1

you plug the y value into one of the equations:

2x - (-1) = -3

2x+1 = -3

2x= -4

x= -2

Factor completely > 16x^2 +48xy + 36y^2​

Answers

Answer:

4 (3 y + 2 x)^2

Step-by-step explanation:

Factor the following:

36 y^2 + 48 x y + 16 x^2

Hint: | Factor out the greatest common divisor of the coefficients of 36 y^2 + 48 x y + 16 x^2.

Factor 4 out of 36 y^2 + 48 x y + 16 x^2:

4 (9 y^2 + 12 x y + 4 x^2)

Hint: | Factor by grouping.

The coefficient of x^2 is 4 and the coefficient of y^2 is 9. The product of 4 and 9 is 36. The factors of 36 which sum to 12 are 6 and 6. So 9 y^2 + 12 x y + 4 x^2 = 4 x^2 + 6 x y + 6 x y + 9 y^2 = 2 x (3 y + 2 x) + 3 y (3 y + 2 x):

4 2 x (3 y + 2 x) + 3 y (3 y + 2 x)

Hint: | Factor common terms from 2 x (3 y + 2 x) + 3 y (3 y + 2 x).

Factor 3 y + 2 x from 2 x (3 y + 2 x) + 3 y (3 y + 2 x):

4 (3 y + 2 x) (3 y + 2 x)

Hint: | Combine products of like terms.

(3 y + 2 x) (3 y + 2 x) = (3 y + 2 x)^2:

Answer: 4 (3 y + 2 x)^2

Answers

Answer: 135.606 m

Try using the law of cosine because if you draw the picture of the triangle out then you see it’s a SAS triangle

C squared equals 320 squared plus 300 squared minus 2 times 320 times 300 times cosine 25

Claire walked her dog 2 1/5 miles. Carson walked her dog 1 3/4 times as far as Claire did. How many more miles did Carson walk her dog than Claire?​

Answers

The word "times" means you have to multiply.

2 1/5 times 1 3/4 is 3 17/20.

The phrase "how many more" means you have to subtract.

3 17/20 minus 2 1/5 is 1 13/20.

Carson walked her dog 1 13/20 more miles than Claire did.

Lori bought a shirt and a hat at a half off sale and she spent a total of 21$ if the shirt was originally 24 how much was the original price of the hat

Answers

Step-by-step explanation:

$21

 

Let the amount Lori bought the shirt and the hat be $x, if she bought them at half off sale, the initial price of both item will be 2 × $x

If she spent $21 on both items, the initial price will have been 2 x $21 = $42 where x is $21

Original price of the hat and shirt is therefore $42. Since both are on half off sale, the initial price is the hat will be $42/2 = $21

Isabela tem dois dados de um jogo, conforme a figura a seguir: O dado 1 é numrado de 1 a 6 e o dado 2 é numerado de 1 a 8. Isabela lançou os dois dados simultaneamente. A probabilidade de que a soma obtida pelos dois números sorteados seja maior que dez é de, aproximadamente: A) 14% B) 15% C) 21% D) 27% E) 29%

Answers

Responda:

C) 21%

Explicação passo a passo:

Dado que:

Dado 1: rotulado de 1 - 6

Dado 2: rotulado de 1 - 8

Espaço amostral :

8 * 6 = 48

Probabilidade = resultado necessário / resultados possíveis totais

Resultado necessário = soma maior que 10 = 10

Resultados totais possíveis = 48

P (soma> 10) = 10/48

P (soma> 10) = 0,208333

20,8333 * 100%

= 20,833%

= 21%

The question is asking for the percentage of absences each week given the percentage of attendance. We can calculate [tex]100\%-Attendance[/tex] (attendance is in percentage form) to find the percentage of people that were absent during each get-together:

Week 1: [tex]100\%-86\%=14\%\\[/tex]
