The cost of tickets to a circus is expressed by the function y = 4x + 2, where
-BARSIC- [3]

Answer:

2

Step-by-step explanation:

This is a linear function, written in the form y=mx+b, where m is the slope, or how many dollars each ticket costs in the case, and b is the initial value of the function, or in this case the cost before any tickets are added to the account.

Since 4x is the slope (4 times however many tickets one purchased), 2 is the initial value before we buy tickets.

You can also plug in 0 for x and get 4(0)+2=2

Hope I helped :D

So far, Ricardo has scores of 13, 17, 19 and 21 points for the first four rounds of a dice game. What does he need the total sco
posledela

Answer:

40 points

Step-by-step explanation:

The score for the first four rounds of the game is 13, 17, 19, and 21 points.

Let S_5 and S_6 be the scores of the fifth and sixth games respectively in order to achieve an average score of 20 points per round for all six rounds.

\text{Average score} = \frac{\text{Sum of the scores of all the rounds}}{\text{Total number of the rounds}}

\Rightarrow 20=\frac{13+17+19+21+S_5+S_6}{6}

\Rightarrow 20\times6=80+S_5+S_6

\Rightarrow S_5+S_6=120-80=40.

Hence, the combined score of the fifth and sixth rounds are 40 points.
