Answer:

option C (3, 2)

Step-by-step explanation:

We have to solve the system of equation by substitution method.

2x + y = 8 ------(1)

y = -x + 5 -------(2)

Now we substitute the value of y from equation (2) to equation (1)

2x + ( -x + 5) = 8

2x - x + 5 = 8

x + 5 = 8

x = 8 - 5

x = 3

Now from equation (2)

y = -x + 5

y = - 3 + 5

y = 2

Therefore, option C (3, 2) will be the answer.

<h3>The formula looks like this: </h3>

(Probability of Winning) x (Amount Won per Bet) – (Probability of Winning) x

(Amount Won per Bet) – (Probability of Losing) x (Amount Lost per Bet).

So, in our example we would plug in these variables, a 50% chance of winning, winning $6, a 50% chance of losing, and $5 lost.

<h3>The formula for expected value = </h3>

(fair win probability) x (profit if win) - (fair loss probability) x (stake).

This is the formula in the OddsJam sports betting expected value calculator.

$\quad\quad\quad\implies\tt{0 + .50 = \frac{2}{3} * \times + 0}$

$\quad\quad\quad\implies \color{blue}\boxed{ \tt \color{red}{.50 = \frac{2}{3}* \times }}$

Therefore, the amount of win is $\tt{.50 = \frac{2}{3}* \times }$

Mark all the statements that are true . A. This graph is a function whose domain is the set 3 B. This graph is a function becaus

nika2105 [10]

The statements that are true are

This graph is a function because the value of x is the same for every value of y
The equation of this line is x = 3. Options B and D

This is further explained below.

<h3>What are the statements?</h3>

Generally, A relation is considered to be a function if it can be shown that each value from the set of first components of ordered pairs is connected with precisely one value from the set of second components of ordered pairs.

In conclusion, You may also consider this in terms of the fact that there is one and only one y associated with each x.

Although it is obvious that this is not the case, the calculation for the vertical line nevertheless uses these terms.
