Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 2x-y=

Bond [772]

Answer:

The system of linear equations has infinitely many solutions

Step-by-step explanation:

Let's modified the equations and find the answer.

Using the first equation:

$2x-y=5$ we can multiply by 2 in both sides, obtaining:

$2*(2x-y)=2*5$ which can by simplified as:

$4x-2y=10$ which is equal to:

$4x=2y+10$

Considering the second equation:

$=4x+ky=2$

Taking into account that from the first equation we know that: $4x=2y+10$ , we can express the second equation as:

$2y+10+ky=2$ , which can be simplified as:

$(2+k)y=2-10$

$(2+k)y=-8$

$y=-8/(2+k)$

Because (-8) is being divided by (2+k), then (2+k) can't be equal to 0, so:

$2+k=0$ if $k=-2$

This means that k can be any number different than -2, and for each of these solutions, there is a different solution for y, allowing also, different solutions for x.

For example, if k=0 then

$y=-8/(2+0)$ which give us y=-4, and, because:

$4x=2y+10$ if y=-4 then $x=(-8+10)/4=0.5$

Now let's try with k=-1, then:

$y=-8/(2-1)$ which give us y=-8, and, because:

$4x=2y+10$ if y=-8 then $x=(-16+10)/4=-1.5$ .

Then, the system of linear equations has infinitely many solutions

A Thurstone scale was constructed to measure creativity. The scale scores ranged from 1 to 13. If the scale was properly constru

Sonja [21]

Answer: A person with a score of 6 was more creative than a person with a score of 5

Step-by-step explanation: The Thurstone scale is usually employed in the representation of non-numerical attributes such as creativity, like or dislike, understanding and so on. in a numerical format usually in questionnaires or surveys in other to denote the level of agreement or disagreement with the statement or create ranking. However, despite being represented in numerical format to create distinction and processing. Variables measured cannot be subjected to mathematical calculation.

In the scenario above, creativity is represented in numerical format to show the level of creativity such that individuals with higher numbers are deemed more creative than those with lesser figures. However, it is wrong to Infer that an individual with creativity score of 6 is twice as creative as those with a creativity of 3.

IT just shows that individuals with 6 are more creativity than those with 5 and so on.

The circumference of a circular rug is 24.8 meters. What is the area of the rug? Use 3.1 for pi

pochemuha

Answer:

49.6 square meters

Step-by-step explanation:

first, circumference is 2*pi*r, so we want to find r. so we take 2*pi*r=24.8 and solve for r which is 4.

Now, area is pi*r^2 so pi*4^2 = pi*16 = 49.6
