Answer:
A. Discriminant = 116
B. Number of solutions for the quadratic equation = 2
C. Type of solutions (circle one):Imaginary
D. Type of solutions (circle one):irrational
Step-by-step explanation:
The given quadratic equation is

We rewrite in standard form to get;

The discriminant is

where a=1, b=8, c=-13
We substitute to get:



Since the discriminant is great than zero, we have two distinct real roots
5 goes with total numbers in the ride
k goes with number of kilometers he has already biked
5-k goes with numbers of kilometers left
and then proces of elimination leaves you with 4 and the last one
Answer:
6,000
Step-by-step explanation:
Answer:
{x,y}={5,4} x is =5 y= to 4
The answer is D. 9(y+3) and 27 + 9y
You would distribute the 9 to both the 3 and the y.
