3x + 4y = -22y - x = -19 what is the solutions ( x , y ) to the system of equations above?
1. 3x + 4y = -22y - x = -19 what is the solutions ( x , y ) to the system of equations above?
Jawab:
(x,y)=(3,-8)
Penjelasan dengan langkah-langkah:
Consider the equations
3x + 4y=-23….(1) and 2y - x =-19….(2)
3*(2)=> 6y - 3x = -57
(1) => 4y + 3x =-23
Adding the above equations we get
(6y - 3x) + (4y + 3x)=-57–23
10y = -80
y=-80/10
y= -8
Put the value of y in equation (2) we get
2(-8)-x =-19
-16 - x =-19
-x =-19+16
-x =-3
x= 3
So the solution is (x,y)=(3,-8)

6. What are the causes of global warming and solutions for our earth.
Jawaban:
Global warming is caused by the increase of greenhouse gases in the Earth's atmosphere. These gases, such as carbon dioxide, methane, and water vapor, trap heat from the sun, causing the Earth's temperature to rise.There are several main causes of this increase in greenhouse gases. One is the burning of fossil fuels, such as coal and oil, for energy. This releases large amounts of carbon dioxide into the air. Deforestation and land use changes, such as the conversion of forests to agricultural land, also contribute to the increase in carbon dioxide by reducing the number of trees that can absorb the gas.
To solve these issues, we can take several actions. One solution is to switch to renewable energy sources, such as solar and wind power, which do not produce greenhouse gases. We can also implement policies to reduce our reliance on fossil fuels and encourage the use of electric vehicles.
Planting trees and protecting forests can also help to absorb carbon dioxide from the atmosphere. In agriculture, we can adopt practices that reduce methane emissions from livestock, such as changing their diet and improving manure management. Overall, to solve the problem of global warming, it is important for individuals, communities, and governments to work together to reduce greenhouse gas emissions and adopt sustainable practices.
