Answer:
C) (1, 12)
Step-by-step explanation:
You can rewrite the equation in vertex form:
y = -4(x^2 -2x) +8 . . . . . factor the leading coefficient from the first two terms
y = -4(x^2 -2x +1) +8 +4 . . . . . add the square of half the x-coefficient inside parentheses (-4)((-2/2)^2) and its opposite outside parentheses (-(-4)).
Now, the equation can be written in vertex form.
y = a(x -h)^2 +k . . . . . . . . . has vertex (h, k)
y = -4(x -1)^2 +12 . . . . . . . . has vertex (1, 12)
______
<em>Comment on the problem</em>
The typewritten form of the equation seems to have a missing leading minus sign. Its vertex is (-1, 4), so "none of the above."
Answer:
91
Step-by-step explanation:
add the given numbers then subtract the solutions from 180. as all triangles sides add up to 180.

About 90 inches for a sports car, or 120 inches for a luxury sedan.
We have the following expression:
4x + 1 = 6x - 2
We clear x of the expression.
We pass the variables to the right and the constant terms to the left:
1 + 2 = 6x-4x
We rewrite the expression:
3 = 2x
We passed the 2 to divide:
3/2 = x
Answer:
The value of x is:
x = 3/2
