what is the correct set of ordered pairs

Using a linear function, it is found that the least possible number of matches played when four players are left is of 339.

A linear function is modeled according to the following rule:

y = mx + b

In which:

For the situation modeled in this problem, we have that:

Thus the average number of players after n matches is given by:

P(n) = 117 - 1/3m.

The least number of matches for there to be 4 players is found when P(n) = 4, hence:

4 = 117 - 1/3m.

1/3m = 113.

m = 113 x 3

m = 339.

Hence at least 339 matches must be played.

The concept used is geometric progression.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r.

Here we can see that shares are being halved per week

we can say that the value of r is 1/2

so we can use the formula of sum of geometric progression to calculate the total number of shares.

sum of geometric progression formula =a(1-r∧n)/1-r

Here we can see that the value of n is 7

On putting the values in the formula we get

sum=24,000(1-1/128)/(1/2)

On further solving we get-

24000×127×2/128 which is equal to 47,625

Hence the total no of shares  of the company he bought are 47,625

Point A' after the dilation of the scale factor by 1/3 is (-1,2) is the correct option.

The given point is;

Point A = (3, -6), scale factor = 1/3

Fortunately, because the dilation is centered at the origin (0,0), we can multiply the scale factor by the x and y-coordinates to acquire the image point coordinates.

Point A' = (3×1/3, -6×1/3)

Point A' = (1, - 2)

As a result, if it grows larger, it should start moving away from the origin, while if it grows smaller (as it does here), this should move closer to a origin.

The missing value of direct variation is 10

The direct variation property states that , whenever the division of values of two quantities is a constant value then there is same variation between these two corresponding values. Or we can also say that if the divisible nature of two corresponding values is constant, then one quantity is directly varies with second quantity. That mean if one quantity increase other will also increase and vice versa.

Let say if x and y are two values and k is a constant value, then

According to direct variation

k = y/x or y = k x

In the given question,

Take the order pair (2,5)

As it is an direct variation, we can substitute it

y=k x  

5=k (2)

K=2.5

Now find the direct variation equation

y=k x

Also, k=2.5

Solve this equation for the second pair (4,y)

As, y=2.5 x

   y= 2.5 (4) = 10

Therefore, missing value is 10

We occasionally discover the value of an unknown variable while solving the system of equations. We can display the graph using the equation, but if the graph and the equation are parallel, we will not be able to solve the system of equations.

We have a condition that, if applied, allows us to determine how many solutions this equation has: if it has one solution, no solutions, or infinitely many solutions.

y = -3 _____(1)

y = x-0.8 _____(2)
