Use the following terms in your answer, Student question: Solve each system by elimination. 1) −4x − 2y = −12 4x + 8y = −24The given system of equations are,-4x - 2y = -124x + 8y = -24Solving the given system of equations by elimination method:

We can obtain 4x from the second equation by dividing the whole equation by 4.4x + 2y = -6Now add the above obtained equation with first equation of the given system of equations.

-4x - 2y = -12+4x + 2y = -6---------------------0x - 0y = -18

Now, there is no unique solution for the given system of equations. Therefore, we cannot determine a value of x and y that satisfies both the given equations.Note:

When we add two equations and the resultant equation is of the form "0x+0y=k",

where k is not equal to zero, then the system has no solution.
To solve the given system of equations by elimination, follow these steps:
1) Write the given equations:
  Equation 1: -4x - 2y = -12
  Equation 2: 4x + 8y = -24
2) Add the two equations together to eliminate the variable x:
  (-4x - 2y) + (4x + 8y) = (-12) + (-24)
3) Simplify the resulting equation:
  -4x + 4x - 2y + 8y = -12 - 24
  6y = -36
4) Divide both sides by 6 to solve for y:
  6y / 6 = -36 / 6
  y = -6
5) Substitute the value of y back into either Equation 1 or Equation 2 to solve for x. We'll use Equation 1:
  -4x - 2(-6) = -12
6) Simplify the equation:
  -4x + 12 = -12
7) Subtract 12 from both sides:
  -4x = -24
8) Divide both sides by -4 to solve for x:
  -4x / -4 = -24 / -4
  x = 6
The solution to the system of equations is x = 6 and y = -6.

Out of the given options, the following is volatile: DRAM and SRAM.

What is Volatile Memory?

A volatile memory is a memory that loses its contents when the power is turned off. The contents of volatile memory, such as RAM (Random Access Memory), are not preserved between power outages or restarts. When the power is turned off, the contents are gone, and they must be reloaded into memory when the system is restarted, causing a temporary delay. Therefore, the DRAM and SRAM are the two volatile memories. DRAM refers to Dynamic Random Access Memory, and SRAM refers to Static Random Access Memory.

What is DRAM?

DRAM stands for Dynamic Random Access Memory. It is a volatile memory that is widely used in computers and other electronic devices to store data temporarily. DRAM chips store data in an integrated circuit that is organized in rows and columns. It allows the computer's processor to quickly read and write data to the memory by accessing a specific row and column intersection.

What is Flash Memory?

Flash memory is a non-volatile computer storage medium that can be electronically erased and rewritten. It is often used in portable devices such as digital cameras, mobile phones, and USB drives to store data temporarily. The data remains in the flash memory even when the device is turned off. It can retain data without a constant power source, making it ideal for data storage applications that require frequent updating, such as digital cameras and music players.

To erase your startup configuration file, you can issue the "erase startup-config" command.

The correct command to erase your startup configuration file is: erase startup-config. A startup configuration file is a file in Cisco network devices that contains configuration commands that are stored in non-volatile memory (NVRAM) and run automatically on device startup. To delete the configuration that is stored in NVRAM, use the "erase nvram" command; this will erase all startup and running configurations. The "erase startup-config" command, on the other hand, will only erase the startup configuration. To delete the running configuration that is stored in RAM, use the "erase running-config" command.

The advantage of writing your own code to check the validity of an input string is that it allows for a more specific set of rules to be applied for validating the string. The disadvantage of writing your own code to check the validity of an input string is that it can be time-consuming and labor-intensive.

For example, you could specify that only certain characters are allowed or that the length must be between certain boundaries. This can be more specific than using regular expressions, which are more of a generalized approach.

In addition, it can be difficult to ensure that all possible scenarios are accounted for, and mistakes may be made in the process of writing the code. This could lead to the code failing to accurately validate the input string in some cases.

Overall, writing your own code to check the validity of an input string can be useful in cases where a very specific set of rules needs to be applied for validation.

If one of the people pointers is free'd, it could lead to an undefined behavior or a segmentation fault.

The people pointers (Steve, Greg, and Matt) in the given image are initialized to point to a character array (name) that stores their respective names. If one of these pointers is freed, it will release the memory that was allocated for the corresponding character array.

However, if the freed pointer is accessed later in the program, it will lead to an undefined behavior or a segmentation fault. This is because the memory that was allocated for the character array is no longer reserved for the program, and accessing it may result in memory errors.

Therefore, it is important to always keep track of memory allocation and deallocation in a program to avoid such issues. It is also recommended to set the freed pointer to NULL after deallocating its memory to prevent it from being used accidentally.
