This questions awnser would be A because if you graph the equations (I use Desmos) you'll see that they all intersect whether it being at one point or infinite except for A which is parallel.
Answer:
3
Step-by-step explanation:
x³ - 3 x² - 13 x + 15 = 0
Basically you can create three factors like this:
(x+3)(x-1)(x-5)=0
That will each represent one zero.
Work it out and you get x³ - 3 x² - 13 x + 15 = 0
