2 (x + 2) & gt; 3 + 2x and Y-3 ≥ 1, who is a unary linear inequality Why is Y-3 ≥ 1 not (⊙ o ⊙?) don't understand (⊙ o ⊙?) don't understand (⊙ o ⊙?) don't understand (⊙ o ⊙?) don't understand
Grasp "one variable (an unknown number) and one time (the highest number of unknowns is 1)" to judge. The first one of this problem is one variable one time inequality
If x + (M-3) y 1 is a linear inequality of one variable about X, the value of M is obtained
Inequality of degree one variable
With X, you can't have y
So M-3 = 0
m=3
If x + y equals 3 ~, then 4 - 2x - 2Y equals?
4-2(x+y)=4-6=-2

- 20. Reading answers of autumn in Three Gorges Read Fang Ji's autumn of the Three Gorges and answer the questions ① It's autumn in the Three Gorges. The autumn of the Three Gorges starts from the orange and pomelo trees on both sides of the river. These trees grow on the steep rocks, and their leaves are as straight as the blue rocks. In autumn, they are more and more green and black, and the fruits are gradually showing up from the green to yellow among the leaves, Make the Three Gorges full of Mature autumn atmosphere ② In the morning, the transparent dew is shining, and the wind in the gorge is cool, as if a layer of white frost is sprinkled on the orange and pomelo trees all over the mountain, fresh and clear; when the sun comes out, the dew disappears, and the orange and pomelo trees are shining with sunshine, green leaves and golden fruit; in the Three Gorges, there is a bright autumn ③ At noon, the peaks are covered with gold armour, the sun is jumping on the water surface, and the Yangtze River becomes warm, like a golden scale python, rolling, whistling and rushing away. On the other hand, it throws its surging and jumping brilliance to the steep cliffs on both sides. So, the whole Canyon is rippling, and the Three Gorges is full of the warm atmosphere of autumn ④ In the afternoon, before the sun sets, a layer of cyan fog rises early in the gorge. This makes the dusk in the gorge come early and go late. Therefore, in the cyan and transparent Huangcuo, the reflections of the cliffs on both sides of the river embrace the center of the river, leaving only a bright sky on the surface of the river. The river flows quietly and gently, becoming like a bright brook ⑤ At last, night comes. The fishing lights on the bank and the lights in the middle of the river light up one after another. Together with the red halo they reflect on the water surface, the Yangtze River seems to blink and sleepy. Only occasionally passing barges, whistling, carve a luminous road on the river. So the fishing lights and lights wake up and sway gently on the water surface ⑥ Perhaps because the mountain here is too high, the canyon is too deep, the sky is too narrow, and even the moon comes very late. At first, in the gorge, you can only feel its hazy blue light, which is connected with the dusk. But I don't know when, it suddenly appears in the same place. It's like growing out of the mountain, it's part of the mountain; it's like a huge, polished, shiny mica stone, The contrast between the moon and the shadow of the mountain is very obvious - the mountain is black like ink, standing steeply, leaning towards the center of the river, as if it is about to plunge down; and the moonlight, from the top of the mountain, along the deep, vertical valleys, spills its bright light all the way to the river. It is like a waterfall, flying down out of thin air; it is like a piece of plain brocade, hanging from the mountain ⑦ This day is the Mid Autumn Festival 1.
