Step-by-step explanation:
we know that
In a quadratic equation of the form
The discriminant is equal to
If D=0 ----> then the system has only one real solution
If D > 0 ---> the the system has two real solutions
If D < 0 ---> then the system has complex solutions
The quadratic equation of the graph has complex solutions
therefore
The discriminant is negative
You would first add 3.60 to 3.60 because there were two people getting smoothies, that gives you 7.20! Without tip the smoothies would cost 6 dollars but we got 7.20 meaning we subtract 7.20 from 6 to get what both friends tipped. That gives you the answer which is 1.20
hope this helps
