I have another problem for your help, so I m in a hurry

Right-click on the desktop.

Remove that what web

Use Optimizer to remove files when putting all the *The lnk files are deleted, so all the shortcuts are invalid. A few suggestions:

1.Take a look at the **station*lnk is still not there, if it is, select the right-click attribute to restore, if it is not there, forget it.

2.Insert the installation disc and run the cmd input"sfc/scannow"(without quotation marks) and wait for the system files to be repaired.

3.After doing the above, it won't work right away, you can use Explorer to open the file, and the system will gradually and automatically re-create the shortcut file*lnk。(up to 3 days).

4.In the future, don't check the lnk file anymore to clean up junk files.

I haven't used the optimization master, but I found some information for you to see.

There are some advanced options in the more settings for users who have some experience with Windows. Including hiding some options in the control panel, locking the desktop, hiding all icons on the desktop, prohibiting the running of the registry regedit, prohibiting the running of any programs, etc.

You go into the settings and find the advanced options (if any), there is definitely an option to hide the desktop icon, just remove this and you're good to go. Or when the system is optimized, see if the hide desktop icon is selected.

You go into Optimizer for recovery, and it has automatic backups in it.

1.Solution:

The focal point is (0,3).

c = 3 and the focus is on the axis.

b²=a²-c²=16

The equation is x b +y a =1

i.e. x 16 + y 25 = 1

2.Solution: Major axis = 2a, minor axis = 2b

2a+2b=20,2a-2b=8

a=7,b=3

The equation is x a + y b = 1 or x b + y a = 1, i.e. x 49 + y 9 = 1 or x 9 + y 49 = 13Solution:

Let the equation be x a + y b = 1

Bring two points into the equation.

2/a²+3/b²=1,4/a²+2/b²=1∴a²=8,b²=4

x²/8+y²/4=1

4.Solution: Let the equation be x a + y b = 1

Bring two points into the equation.

2/a²+1/b²=1，3/a²+1/2b²=1∴a²=4,b²=2

x²/4+y²/2=1

24 divided by 8 = 3 (yuan kilograms).

24 divided by 6 = 4 (yuan kilograms).

24 divided by (3+4)=3 (kg)·· 3 (yuan) can buy three kilograms.

Hope landlord.
