Answer:
x = 6 (A)
Explanation:
We plug y = x^2 - 5x + 3 into 5x + y = 39 and we have
5x + x^2 - 5x + 3 = 39
-> x^2 = 36
-> x = 6
Answer:
where is the Missing words
The two options would be to reduce the demand for energy and or use renewable sources of energy. Options C and D are correct.
<h3>How to reduce carbon emission</h3>
The burning of fossil fuels such as coal and crude oil-derived fuels generates a large amount of emissions.
In order to cut down on the emission, the demand for energy needs to be lowered by all means. In addition, instead of using fossil fuels, renewable sources of energy can be used.
Greenhouse gases such as carbon dioxide, oxides of sulfur, and water vapor are produced largely as by-products of burning fossil fuels. These gases form a layer in the atmosphere and trap reflected solar radiation.
By doing so, the increase the average annual temperature of the planet (global warming). The warming of the planet has several negative effects on the climate and the ecosystems as a whole.
Renewable sources of energy, on the other hand, have very little to no greenhouse gas emissions.

Answer:
The equilibrium in the system is a dynamic equilibrium. At equilibrium, the rate of the forward reaction (CH4 decomposing into C2H2 and H2) is equal to the rate of the reverse reaction (C2H2 and H2 reacting to form CH4). At equilibrium, the concentrations of all substances are not changing.
