Answer:
B
Step-by-step explanation:
The given equation y = 2x^2 -12x - 32 can be factored as follows:
y = 2(x^2 - 6x - 16) = 2(x - 8)(x + 2). Then its roots are x = -2 and x = 8.
Since d > e and 8 > -2, we conclude that d = 8 and e = -2.
We need to find the minimum of y = 2x^2 -12x - 32.
We can do this by finding the vertex: b
The equation of the axis of symmetry is x = - ----------
2a
-12
which here is x = - --------- = 3
2(2)
so f = 3.
Answer choice B is correct.
Answer:
y = -10x +44
Step-by-step explanation:
Parallel lines will have the same slopes but different b values so we know that the base of this equation will be
y = -10x +b
To find b we must plus in the given coordinates and determine which value of b makes the statement true.
-6 = -10(5) + b
-6 = -50 + b
b = 56
Therefore the new equation will be:
y = -10x + 44
