Answer:
B. a = 4, b = -8, c = -3
Step-by-step explanation:
The quadratic equation given is:

The general form of a quadratic equation is given as:

Let us put the given equation in this form and then compare with the general form of the quadratic equation.

Therefore, by comparing:
a = 4
b = -8
c = -3
The correct option is B
Answer:
k < - 1
Step-by-step explanation:
28 + 3k < 5(-3-8k)
28 + 3k < - 15 - 40k
28 + 15 < - 40k - 3k
43 < - 43k
43/- 43 > k (switch signs because 43 is negative)
k < -1
