Answer:
b i got it right
Step-by-step explanation:
-4x=-x2+12 should be written <span>-4x=-x^2+12, with " ^ " representing exponentiation.
You are to invent a table of x values and find the difference between -4x and -x^ 2+12. The smaller the difference, the closer you are to finding the correct root, x.
To get you started:
x -4x x^2+12 difference
--- ------------ ---------------- --------------
2 -8 16 24 (pretty bad!)
-4 16 28 12 (better)
-10 40 112 72 (much worse)
To answer this problem correctly, you must present such a table, even tho' it'd be faster to use the quadratic formula (or some other method) to find x.

If the shape is the same, but the size is different, <em>dilation is involved</em>. There may be other transformations that are also involved (such as rotation, translation, or reflection), so MNPQ may or may not be a straight dilation of M'N'P'Q'.
_____
Translation and dilation can sometimes be combined to a dilation about a point that is not the origin. Reflection might be accommodated by using a negative dilation factor. However, rotation cannot be accomplished using dilation alone.

plug in (-1) for x, this gives you (-2)(-1)+3 which is (2)+3 =5
