Answer:
Explanation:
y2-y1 over x2-x1
-1+1 over 2-4
0/-2= m=0
y=mx+b
-1=0(2)+b
-1=0+b
b=undefined
so basically the equation is undefined so you can say x=to whatever number
Answer:
Paleozoic
Explanation:
The first insect fossils are dated to the Devonian, but because of the development of the genetics, the scientists have been able to trace the appearance of the first insects in the Ordovician. The insects originated from the crustaceans. Initially they were walking on land, but they hadn't developed wings. The wings came to develop in some insects in the Devonian, and since than it has gradually became one of their trademark features. It is interesting that the first insects actually appeared at the same time with the first terrestrial plants, and also that they are the first organisms to develop wings and be able to fly.
Answer:
(C) Metropolitian Area
Explanation:
Metropolitian Areas are those that are developed. This answer makes the most sense because a developed area is one that people have grown in and settled.
Hope this helps!
Answer:
Agriculture is the main source of food, income, and employment of our country. ... Agriculture has been the highest priority because economic growth was dependent on both increasing the productivity of existing crops and diversifying the agricultural base for use as industrial inputs.

Modern agriculture is an evolving approach with innovations in farming practices that helps in increasing agricultural efficiency and reduce the loss of natural resources. By applying this modern technology, farmers are gaining more profits and able to increase their productivity of field.
Some of the modern techniques like selected variety of hybrid seeds of a single crop; bio-fertilizers and bio-pesticides; technologically advanced equipment and energy subsidies in the form of irrigation water are commonly employed by the farmers. The sensors used to detect moisture in the soil help farmers to create irrigation systems for crops based on soil moisture and temperature. Working in low visibility field conditions like rain,dust and fog is possible with the help of modern technologies. Agricultural robots automate agricultural processes of fruit picking, crop harvesting, soil maintenance, irrigation, ploughing, planting, weeding and others. These robots automate slow and repetitive tasks for farmers to ensure focus on improving overall production yields. Land-augmenting technological changes involve technical, chemical and biological modifications to beintroduced in agriculture.
For earthquakes, there is a lapsed time between the arrival of the
p-wave and the s-wave, because the waves travel at different speeds. The length
of this period of time determine the
distance to the epicenter.
Earthquakes create seismic waves. P waves are faster than S
waves. As the P and S waves move out from an earthquake, the P waves get ahead
of the S waves. The distance of a seismic station from an earthquake can be
determined from the time difference between the time of arrival of the first P
wave and the first S wave.
