one variable and systems of equations in two variables · 原库模块 1 · Q6 原库参考解析
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 \( a=\frac{vf-12}{5} \) , where vf is the final velocity of the object in meters per second. If the equation is rewritten in the form vf = xa + y, where x and y are constants, what is the value of x ?
