Using substitution what is the value for x for the equations 2x+y=-3 and
y=4x+6? *
X3
x=3/2
O
x=0​

Answers

Answer 1

Answer: x = -3/2

Explanation:

Hi, to answer this question we have to solve the system of equations:

2x +y =-3

y=4x+6

Substituting y=4x+6 in the first equation:

2x + (4x+6) =-3

Solving for x:

2x +4x+6 =-3

2x+4x =-3-6

6x =-9

x =-9/6

x = -3/2

In conclusión, the value of x is -3/2.

using substitution what is the value for x for the equations 2x+y=-3 and y=4x+6​

Answers

Answer:

[tex]x = \frac{-3}{2}[/tex]

Explanation:

Given

2x + y = -3

y = 4x + 6

Required

Find the value of x

2x + y = -3 --- Equation 1

y = 4x + 6  --- Equation 2

Substitute 4x + 6 for y in equation 1.

So, equation 1 becomes

[tex]2x + 4x + 6 = -3[/tex]

[tex]6x + 6 = -3[/tex]

Subtract 6 from both sides

[tex]6x + 6 - 6 = -3 - 6[/tex]

[tex]6x = -9[/tex]

Divide both sides by 6

[tex]\frac{6x}{6} = \frac{-9}{6}[/tex]

[tex]x = \frac{-9}{6}[/tex]

Simplify fraction

[tex]x = \frac{-3}{2}[/tex]

Hence, the value of x is [tex]x = \frac{-3}{2}[/tex]

Write an algorithm and draw a flowchart to input two numbers from the user and display the largest of two numbers

Answers

Answer:

Explanation:

Required

- Algorithm to display largest of two numbers

- Flowchart to display largest of two numbers

Algorithm

1. Start  

2. Input num1, num2

3. Largest = num2

4. If num1 > num2 Then

4.1 Largest = num1  

4. Print Largest

5. Stop.

See attachment for flowchart

To do this, three variables (num1, num2 and Largest) are used.

The algorithm starts by inputting values for num1 and num2; Then variable Largest is initialized to num2

If num1 is greater than num2, the value of Largest is changed to num2; else, nothing changes

Then Largest is printed.

The algorithm and flowchart which evaluates the larger of two numbers is given below and the flowchart attached :

The algorithm :

Step 1 : Start

Step 2 : Reads in two values a and b

Step 3 : Using the comparison operator, check if a is greater or b is greater

If a is greater, display a is greater, otherwise, b is greater.

Step 4 : Stop

The algorithm above gives the stepwise approach to finding the larger value. The graphical order of instruction called the flowchart is attached.

In tropical regions, where temperature and precipitation are consistently high, thick soils form.

Explanation: Hope this works

They are created from rocks (the parent material) by weathering and erosive forces of nature. Parent material is broken down by a variety of factors, including water, wind, gravity, temperature change, chemical reactions, living things, and pressure variations.

What are the factor involving in the formation of soil?

Parent materials' rate of weathering and, consequently, soil characteristics like mineral composition and organic matter concentration are influenced by temperature and precipitation.

Faster plant and bacterial growth in warmer climates aids in the weathering of materials and the formation of soils. Thick soils develop in tropical areas where the temperature and precipitation are both constantly high.

Therefore, The rate of chemical reactions is accelerated by rising temperature, which also accelerates soil formation.

write a paragraph on plastic and pollution within 100 words

Answers

Plastic is everywhere nowadays. People are using it endlessly just for their comfort. However, no one realizes how it is harming our planet. We need to become aware of the consequences so that we can stop plastic pollution. Kids should be taught from their childhood to avoid using plastic. Similarly, adults must check each other on the same. In addition, the government must take stringent measures to stop plastic pollution before it gets too late.

Plastic has become one of the most used substances. It is seen everywhere these days, from supermarkets to common households. Why is that? Why is the use of plastic on the rise instead of diminishing? The main reason is that plastic is very cheap. It costs lesser than other alternatives like paper and cloth. This is why it is so common.

Secondly, it is very easy to use. Plastic can be used for almost anything either liquid or solid. Moreover, it comes in different forms which we can easily mold.

Furthermore, we see that plastic is a non-biodegradable material. It does not leave the face of the Earth. We cannot dissolve plastic in land or water, it remains forever. Thus, more and more use of plastic means more plastic which won’t get dissolved. Thus, the uprise of plastic pollution is happening at a very rapid rate.

Most importantly, plastic pollution harms the Marine life. The plastic litter in the water is mistaken for food by the aquatic animals. They eat it and die eventually. For instance, a dolphin died due to a plastic ring stuck in its mouth. It couldn’t open its mouth due to that and died of starvation. Thus, we see how innocent animals are dying because of plastic pollution.

In short, we see how plastic pollution is ruining everyone’s life on earth. We must take major steps to prevent it. We must use alternatives like cloth bags and paper bags instead of plastic bags. If we are purchasing plastic, we must reuse it. We must avoid drinking bottled water which contributes largely to plastic pollution. The government must put a plastic ban on the use of plastic. All this can prevent plastic pollution to a large extent.
