Acard game has 50 cards. after dealing 7 cards to each player, tupi has 15 cards left over. solve the equation 50-7p=15 to find the number of players.

50 - 7p = 15subtract 50 from both sides
-7p = 15 - 50
-7p = - 35...divide both sides by -7
p = -35/-7
p = 5 <=== there are 5 players

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
