Choose the equation that could be used to find two consecutive integers whose sum if 57. x - (x + 1) = 57 x + (x + 1) = 57 x + (x + 2) = 57. x + x = 57

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%
