Answer:
The answer is C
Step-by-step explanation:
The question is first asking us to multiply 28x2, which equals 56. We're going to then round 56 to the nearest ten. The six is greater than five, so we round up,many we're going to round up to 60. So, 60 is your answer.
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
The point slope equation should be y+1=2(x-6)
