Answer:
The graph has only one x-intercept
Step-by-step explanation:
we have

we know that
The discriminant of a quadratic equation of the form
is equal to
in this problem we have

so

substitute
The discriminant is zero
That means ----> The quadratic equation has one real solution
The graph has only one x-intercept
1500km divided by 90km = 16.6666667, so therefore it is 16 hours and 36 minutes. add that to 9:30, it arrives at 2:06am on Wednesday.
We have to factor the polynomial.
x^8+3x^5
Find the GCF between 1,3,x,5,8
The GCF is x^5
Divide the polynomial by x^5
x^5(x^3+3)
