If y varies directly as x, and y is 12 when x is 1. 2, what is the constant of variation for this relation?.

Last year, a state university received 3,560 applications from boys. of those applications, 35 percent were from boys who lived in other states. part a)how many applications did the university receive from boys who lived in other states? part b)applications to the university from boys represented 40percent of all applications. how many applications did the university receive in all? i don't how to do part b so me and plz tell how you got your answer

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29
