Question 9c2a8ff4

During a 5-second time interval, the average acceleration a, in meters per second squared, of an object with an initial velocity of 12 meters per second is defined by the equation $a equals, the fraction with numerator v subscript f, end subscript, minus 12, and denominator 5$ , where v_f is the final velocity of the object in meters per second. If the equation is rewritten in the form v_f = xa + y, where x and y are constants, what is the value of x ?
