A quadratic equation has exactly one real number solution.
For any quadratic equation the discriminant D is 
When discriminant D> 0 then there will be 2 real solutions
When discriminant D= 0 then there will be 1 real solution
When discriminant D< 0 then there will be 2 complex solutions
Question says 'A quadratic equation has exactly one real number solution'
So Discriminant D =0
The number of miles that he will have traveled after 3.5 hours of driving on the highway is 227.5 miles.
The function given to solve the question is: f(x) = 65x
where, x = number of hours
Therefore, when he travelled for 3.5 hours, the number of miles will be gotten by multiplying 65 by 3.5.
f(x) = 65x
= 65 × 3.5
= 227.5 miles.
Therefore, the number of miles that he will have travelled after 3.5 hours of driving on the highway is 227.5 miles.

I can not answer the question sorry
7 because 6 gives you 7.6 which is smaller than 8.6 so it would be 7.
Answer: 17/2
Step-by-step explanation:
Step 1
Multiply the denominator by the whole number
2 × 8 = 16
Step 2
Add the answer from Step 1 to the numerator
16 + 1 = 17
Step 3
Write answer from Step 2 over the denominator
17/2
=172
