Need asap plzin a chess competition players can participate in up to 6 games .each player's total score for the competition will be calculated according to the function t = 40 + 10 w, where w represents the number of wins what is the domain and the range for the function for the situation.

The domain of the function for the given situation is defined by the set {0, 1, 2, 3, 4, 5, 6} and the range is defined by the set {40, 50, 60, 70, 80, 90, 100}.

Explanation:

Domain in the set of inputs and range is the set of outputs.

The function is defined as,

Where w represents the number of wins.

Since it is given that in a chess competition players can participate in up to 6 games, therefore he can win 0 to 6 games.

So, the values of w can be 0, 1, 2, 3, 4, 5 and 6.

Find the value T for the above values of w.

For w = 0

For w = 1

For w = 2

For w = 3

For w = 4

For w = 5

For w = 6

The the function can take value 40, 50, 60, 7, 80, 90 and 100.

Therefore, the domain of the function for the given situation is defined by the set {0, 1, 2, 3, 4, 5, 6} and the range is defined by the set {40, 50, 60, 70, 80, 90, 100}.

answer: i guess 5 units?

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
