Because the parabola intercepts the x-axis only once, we conclude that the discriminant is 0.
<h3>
What can we say about the discriminant?</h3>
For a quadratic equation:
y = a*x^2 + b*x + c
The discriminant is:
D = b^2 - 4ac
- If D = 0, there is only one real zero.
- If D > 0, there are two real zeros.
- If D < 0, there are two complex zeros.
In the graph we can see that the parabola intercepts the x-axis in its vertex, then the parabola has only one real zero, then we conclude that the discriminant is equal to zero.

Answer:
this is the answer of your question

Let the number of sheet she buy be x.
Therefore the equation is
y = 5x + 8
Hope it helps
In this problem the amount of kilograms you want to fit ( lets call it x ) has a direct variation with the amount of kg of soil it can fit in ( lets cal it y )
If 2/5x = 1/3y
Now we just need to isolate x or y to discover the proportion that relates them :
You can isolate x by multiplying both sides of the equation by 5/2
2/5x(5/2) = 1/3y(5/2)
x = 5/6 y
So what that means is that 1 kg of soil takes 5/6 of the container!
