I NEED THE ANSWER AS SOON AS POSSIBLE PLS Solve the system of equations {4x + 6y = 24
pair for its solution.
2x + y = 8 which has exactly one (x, y)

i only need number 4

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°

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.
