What of the following us a solution to the system of equations​

Mathematics
1 answer:
andriy [413]3 years ago
4 0

Answer:

(- 1, - 5 )

Step-by-step explanation:

Given the 2 equations

y = 3x - 2 → (1)

6 + y = - x → (2)

Substitute y = 3x - 2 into (2)

6 + 3x - 2 = - x

4 + 3x = - x ( add x to both sides )

4 + 4x = 0 ( subtract 4 from both sides )

4x = - 4 ( divide both sides by 4 )

x = - 1

Substitute x = - 1 into (1) for corresponding value of y

y = 3(- 1) - 2 = - 3 - 2 = - 5

solution is (- 1, - 5 )

A cell is a basic unit of structure and function of all living things.

A tissue is a group of cells that work together to perform a common function.

Step-by-step explanation:

The different levels of organization in living things are defined below from smallest to largest:

Cell is the smallest unit of life. It is the basic structural, functional, and biological unit for all living things.

Tissue is a group of cells working together to accomplish a special function. Examples of tissue are connective tissue, muscle tissue.

Organ is a group of tissues working together to perform a specific function. Examples of organs are heart, liver etc.

System is a group of organs working together to perform a particular task and provide stability to the body. Example is muscular system, nervous system etc.

Organism consists of a group of system working together to perform a specific function. An organism is a living thing with an organized structure

Which of the expressions below can be factored using the difference of squares method? A. 25x2 - 64y2 B. 17x2 + 23y2 C. 17x2 - 2
denis-greek [22]
<span>Difference of squares method is a method that is used to evaluate the difference between two perfect squares.

For example, given an algebraic expression in the form:
x^2-y^2
can be factored as follows:
(x-y)(x+y)

From the given expressions, the only expression containing two perfect squares with the minus sign in the middle is the expression in option A.
i.e. 25x^2-64y^2
which can be factored as follows:
(5x-8y)(5x+8y).</span>

Como podríamos saber cuantos camellos le corresponden a cada hermano en realidad
SCORPION-xisa [38]

Answer:

Eldest brother = 18 camels

2nd brother = 12 camels

Youngest brother = 4 camels

Step-by-step explanation:

Question posted:

How could we know how many camels actually correspond to each brother?

It is from "the man who calculated":

The question is incomplete without the background information.

Based on the question, It has to do with sharing an inheritance of 35 camels among 3 brothers.

"The man who calculated", by Malba Tahan.

Since the complete question isn't available, we are going to look at the following question to understand how to do the calculation.

Question:

How can an inheritance of 35 camels be divided among three brothers in such a way that the eldest brother gets half of them, the second one gets 1/3 of the total and the youngest brother gets 1/9 of the total camels?

Solution:

Total number of camels= 35

Eldest brother gets half: 1/2 of 35 gives a fraction and not an whole number

2nd brother = 1/3 of 35 (gives a fraction)

3rd brother = 1/9 of 35 (gives a fraction)

Since we can't have a camel in fraction except in whole number, we would look for the closest number to 35 that would be divided by 2, 3 and 9 respectively without giving a fraction.

Number 36 is the closest number to 35 that satisfies this condition.

1st brother = 1/2 × 36 = 18 camels

2nd brother = 1/3 × 36 = 12 camels

3rd brother = 1/9 × 36 = 4 camels

Now let's add the camels the 3 brother got together = 18 + 12 + 4 = 34 camels

Total camels - amount shared = 35 -34 = 1

Meaning one camel is remaining. The distributor would keep the remaining one as that's the way such distributions could be achieved.
