Answer:

$\boxed{2}$

Explanation:

$(x+3)(x-1)$

Expand the brackets.

$x(x-1)+3(x-1)$

$x^2-x+3x-3$

Combine like terms.

$x^2+2x-3$

The coefficient of $x$ is $2$ .

The system software has three major functions which are:

1. File and disk management: this involve managing of files in the system, when user want to save, move, copy, delete and rename files, The system software will handle those task

2. Allocating system resources: The system resources such as time, memory, data input and output are allocated by the system software. The main memory is managed by the system software to avoid conflict among various task.

3. Monitoring system activities: The system security and system performance is also monitored by the system software.

Find the equation of a line which has 10 points the following two coordinates: (4, 0) and (3, 4)

alex41 [277]

Answer:

The equation of the line is y = -4·x + 16

10 points on the line include;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

Explanation:

The given points through which the line passes are;

(4, 0) and (3, 4)

The slope, 'm', of the line is given as follows;

$Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Therefore, the slope of the line is (4 - 0)/(3 - 4) = -4

In point and slope form we can get;

$\dfrac{y-0}{x-4} = -4$

The equation of the line in point and slope form is therefore;

y = -4·(x - 4) = -4·x + 16

The equation of the line in slope and intercept form is

y = -4·x + 16

10 points on the line are obtained using the equation of the line and the desired x-values input into cells on MS Excel and presented here as follows;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

Answer:

D. Fault tolerance

Explanation:

Fault Tolerance basically refers to the feature or capability of a system to keeps on working and performing its operations without interruption in case of a failure.
This failure can be the failure of one or more of its components.
This is beneficial as the system does not stop working or fail completely.
It provides copies of the same system or backup components which can be used when the existing system fails and prevents the loss of information and services.
Accessibility refers to provide equal services for everyone who uses a system. So its not a correct option.
Moore’s law states that the computing speed and power will double every two years so its not a correct option as well.
Anti virus is a software to identify, prevent and remove viruses and malware so it is not a correct option as well.
