The equation may also have one common root or no real roots. This gives the maximum number of points where the parabola<span> intersect as </span>2<span>. ... When that is the case, the twp </span>parabolas<span> intersect at 4 </span>distinct<span> points. The maximum number of points of intersection of </span>two distinct parabolas<span> is 4.</span>
The answer would be 13.6
You can find out by setting this up as a proportion
Now cross multiply 5 x 1 = 5 and now divide 68/5 = 13,6 and we can check this by multiplying 13.6 x 5 = 68 so we know our 13.6 is correct
