For this case suppose that we have a quadratic equation of the form:

The solution to the quadratic recuacion is given by:

Where,
The discriminant is:

When the discriminant is greater than zero, then the root is positive, and therefore, we have two positive real solutions.
Answer:
B. it has two real solutions
Answer:
(-1, 7, 2)
Step-by-step explanation:
we suppose that ax + by + cz = d for the matrix
D = det [ 0 4 7] = 100
-6 0 -2
1 2 8
Dx= det [ 14 4 7] = - 100
10 0 -2
-3 2 8
Dy= det [ 0 14 7] = 700
-6 10 -2
1 -3 8
Dz = det [ 0 4 14] = 200
-6 0 10
1 2 -3
So the solution is:
x = Dx/D = -1, y = Dy/D= 7, z =Dz/D = 2
(-1, 7, 2)
have a good day!
The answer to X is = 369700
Answer:
4 divided by 2 = 2
Step-by-step explanation:
If there are 4 chocolate bars and 2 sisters then each sister gets 2.
One decimeter is one tenth, or 0.1, of a meter. So multiply 50 meters by 0.1 (one decimeter). The answer is 5 decimeters in a race that is 50 meters.
