Sam went to play video games in Video Game Central arcade. Video Game Central charges $10 to get into the arcade and then $1 per game played. Represent the
relationship between total cost, y, and number of games played, x using a table, graph and
equation. Is this relationship a proportional or additive relationship? Explain.

additive relationship

Step-by-step explanation:

Since y or $10 is only the amount to get in, you will only need to pay $10 once.  

BUT, you need to play $1 PER game. For every game you play, you add 1 dollar.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
