Lin is solving the inequality 15-x< 14. She knows the solution to the equation 15 - 1 = 14 is r = 1

How can Lin determine whether x > Torx < I is the solution to the inequality?

Situation: an archaelogist in turkey discovers a spear head that contains 54% of its original amount of c-14. n = noekt no = inital amount of c-14 (at time t = 0) n = amount of c-14 at time t k = 0.0001 t = time, in years find the age of the spear head to the nearest year
