Determine whether the formula describes y as a function of x. explain your reasoning.

y = -x

If you had $1,900,000, how many days would it take you to spend all if you spent $1 a second. (there are 86,400 seconds in a day)

Negative 5 1/12 + negative 4 1/4 + 6 3/4

What are the solutions of the system? y = x^2 + 2x +3y = 4x - 2a. (-1, -6) and (-3, -14)b. (-1, 10) and (3, -6)c. no solutiond. (-1, -6) and (3, 10)
