Answer:
D
Step-by-step explanation:
Since we already know what -y is we can use that to find y.
y = -5x -21.
Let's substitute that in the bottom equation
-4x -5x - 21 = 6.
Simplify.
-9x = 27.
x = -3
Let's solve using
y = -5x -21.
to find y.
y = -5(-3) - 21
y = 15 - 21
y = -6.
There you have it!
x = -3, y = -6
So.. The correct answer choice is D
I think the answer is 119
Answer:
Below in bold.
Step-by-step explanation:
y = -4x2 + 8x - 13
Divide first 2 terms by -4:-
y = -4(x^2 - 2x) - 13
Convert to vertex form by completing the square:
y = -4[(x - 1)^2 - 1] - 13
y = -4(x - 1)^2 + 4 - 13
y = -4(x - 1)^2 - 9 <---------- Vertex form
y = a(x - j)^2 + k <---------- General form with vertex = (j, k).
So comparing, we see that the vertex is (1, -9).
