Only by making the problem clear can someone help.

0 0 I don't understand what you're talking about!! What is the problem???

Van x Coach Y

x+y=75

4x=y gives x=15 and y=60

Question 1: According to the conditions, if Xiaodong has x extracurricular books, then Xiao Ming's extracurricular books are 2x. List Formulas:

3 (2x-10) = x+10, Ming Jinyuan (after Xiao Ming gave Xiao Dong 10 books, Xiao Dong's books were 3 times the remaining number of Xiao Ming, so Xiao Ming's books had to be multiplied by 3 to be equal to Xiao Dong). Calculation: 6x-30=x+10 5x=10+30 x=8 then 2x=16.

That is, Xiaodong originally had 8 copies, and Xiao Ming had 16 copies.

The second question can't see the number of the pattern, you can set the carnation x yuan, daffodil y yuan, the first bunch is 3x+y=how much, the second bunch is 2x+2y=how much, in solving this quadratic equation, get the number of x, y, the price of the third bunch is the sum of x+3y.

You will have 30 minutes to plan and write an essay on the topics given below. Use the first few minutes to read the topic and think carefully about what kind of article you will write. You can use the space to take notes on the following topics at once.

Your article is written on the page, following the wrinkles. You will have plenty of space if you write on each line, keeping your calligraphy to a reasonable size.

Some people believe that we should spend as much money as possible to explore outer space (e.g., travel to the moon and other planets). Others disagree, believing that we should spend this money for our basic needs on Earth. Do you agree with these two points of view?

Support your response with specific reasons and details.

Obviously, it is a hard disk problem, one is the problem of the hard disk itself, it is recommended to back up the data, change the hard disk, and the second is the contact problem of the hard disk, it may be that the computer has fallen, or the contact site is loose, it is recommended to disassemble and reinstall.

f'(x)=1/x-2 f(1)=-2

f'(1)=-1

Then the tangent of the curve y=f(x) at x=1 is y+2=-1(x-1), that is, x+y+1=0

So the intersection point with the x-axis is (-1,0) and the intersection point with y=g(x) is (1 (m+1),m (m+1)).

So s=1 2*1*|m/(m+1)|=1/8m/(m+1)|=1/4 16m^2=m^2+2m+115m^2-2m-1=0

3m-1)(5m+1)=0

m=1/3 ,-1/5

f'(x)=1 x-2=(1-2x) x, then f'(1)=-1 and f(1)=-2;

So, the tangent equation is: y+2=-1(x-1) i.e. y=-x-1

The intersection of y=-x-1 and y=mx is (-1 (m+1),-m (1+m)), so: (1 2)*1*l-m (m+1)l=1 8

Solution: m=1 3
