What do young people think about places in town? Wedid a survey of our readers and this is what we learned. All the movie theaters are good, but the Screen City is the best in our town. It has the biggest screens and the most comfortable seats. However, Town Cinema is the cheapest, and it has the friendliest service. The most popular clothing store is Jason's . It has the best quality clothing. It's also the cheapest. Funky Fashhinos is the worst. It has really bad service. As for radions, most people think that Jazz 107.9 FM is really great. It plays the most interesting muisc.
Last week;s talent show was a great success.There were fifteen acts.Eliza won the prize for the bast performer.She played a beautiful piano piece.Hu Yue was the quietest performer.He danced without music.The prize for the funniest act went to Steve Tian and his dog, Fido.They sang a cute song together.

Here's what two of our students said about our school when I was a young girl, all I ever wanted to do was travel, and I decided that

In ten years, I think I will become a journalist. I will live in Shanghai, because I went to Shanghai last year and fell in love with it at first sight. I think it's really a beautiful city. As a journalist, I think I will meet many interesting people. I think I will be with my best friend

How to calculate 4.78-1.28 + 1.22-0.72

4.78+1.22-（1.28+0.72）=6-2=4

Given that x = 3, y = - 2 is the solution of AX = by = 6, 2ax-3by = 12, find the value of a-2b
Given that x = 3, y = - 2 is the solution of AX + by = 6, 2ax-3by = 12, find the value of a-2b.
The above question is wrong

If yes
AX+BY=6,2AX-3BY=12
X = 3, y = - 2 are the solutions of the equations
3A-2B=6
6A+6B=12
A = 2, B = 0
So a-2b = 2
If ax-by = 6, 2ax-3by = 12
3A+2B=6
6A+6B=12
A = 2, B = 0
So a-2b = 2

Is there a simple algorithm for 20 out of 21 △ 11 out of 18 × 11 out of 15 △ 2 out of 35 [(1 out of 5-1 out of 6) △ 5 out of 24]?

20/21÷11/18x11/15
=20/21x18/11x11/15
=40/35=8/7
2/35÷（（1/5-1/6）÷5/24）
=2/35÷（1/30÷5/24）
=2/35÷4/25
=10/28

If the image of function y = ax ^ 2 (a is not equal to 0) is above the line y = 2x-3, the value range of a is obtained

Obviously, a > 0, parabolic opening upward
Let ax ^ 2 = 2x-3, ax ^ 2-2x + 3 = 0
There is no intersection between the two images
△=4-12a1/3

General score: 5 / 18 and 15 / 28

5/18=70/252
15/28=135/252

E-integral of exponential function
How can I find the integral of the - 2x power of 2 times e from zero to positive infinity? I think the answer is 1 / 2. How can I find it,

It's a half,
Put the coefficient 2 after D, add a minus sign before and after D, and use y instead of - 2x. You should understand the rest, unless you are a high school student
It's not convenient to edit the integral number here

How much is 1 times 2 / 1 plus 2 times 3 / 1 plus 3 times 4 / 1 plus 4 times 5 / 1 plus 5 times 6 / 1 plus 6 times 7 / 1

1 by 2:1 plus 2 by 3:1 plus 3 by 4:1 plus 4 by 5:1 plus 5 by 6:1 plus 6 by 7:1
=1-1/2+1/2-1/3+1/3-1/4+1/4-1/5+1/5-1/6+1/6-1/7
=1-1/7
=6/7
=6 out of 7
