Answer:

(1 , -2/3)

Step-by-step explanation:

when y =0

3×0-2x=-2

0-2x=-2

divide both side by -2

x=1

when x=0

3y-2×0=-2

3y-0=-2

divide both side by 3

y=-2/3

Jacob estimates the square root of 75 in the following way:
pav-90 [236]

Answer:

a)

Step-by-step explanation:

Square root of 75 (√75) is regarded as a surd function because the value inside the square root sign is not a perfect square. In that case the given value will be splitted into the product of a largest perfect square and a prime number as shown:

√75 = √3×25

√75 = √3×√25

√75 = √3 × 5

√75 = 5√3

a) Based on the above calculation, it can be inferred that his reasoning is incorrect. The value of 3 was supposed to be inside a square root not a whole number i.e √3 × √25

b) Since √75 = 5√3

√75 = 5 × 1.7321

√75 = 8.6605

√75 = 8.661 {to nearest thousand}

Sabendo-se que 9 174 532 x 13 = 119 268 916, pode-se concluir que é divisível por 13 o número:
Effectus [21]

Answer:

A

Step-by-step explanation:

Sabendo que 119 268 916 é divisível por 13, o número 119 268 903 também é divisível por 13.

Isso ocorre porque a diferença entre um múltiplo de um número e o próximo múltiplo de um número é esse próprio número.

Portanto, para encontrar outros múltiplos que são divisíveis por 13 dado o resultado na pergunta, podemos adicionar múltiplos menores de 13 ou subtrair múltiplos menores de 13 do número.

O que estamos dizendo é que o número - 13 ou mesmo -26 ou +39 daria outro múltiplo de 13. O que estamos dizendo é que chegaremos a um número que é divisível por 13 do outro número dado que o número que estamos adicionando ou subtrair do número é um múltiplo de 13.

Agora vamos verificar as opções, podemos ver que a diferença entre o número e a opção é 13 que, claro, é um múltiplo de 13.

Esta é a razão pela qual o número é a nossa resposta.

Pls help I need it pls
Whitepunk [10]

Answer:

Step-by-step explanation:

First, in millimeters, so the first square is 2025, and the second square is 900. Add those to get 2925 mm. Then, look at the answers. Whichever one has 2925 mm squared first, then a smaller number, that's the one. Therefore, the answer is 2925 mm squared and 29.25 cm squared.
