I NEED HELP AND FAST! Consider the following pair of equations: y = x + 4 Y = -2x - 2 Explain how you would solve the pair of equations by substitution. Explain your answer

If you roll two fair dice (one black die and one white die), in how many ways can you obtain a 4 on at least one die?

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2
