Step-by-step explanation:
The vertex is the point (-4, 7).
Answer: $5.41
Since you have find c, how much more the second poster costs, you have to subtract from $12.45.
12.45 - 7.04 = 5.41
Answer = $5.41
Reflectional symmetry<span> exists when the figure can be folded over onto itself along a line. This line is called the "line of symmetry". The correct answers for this would be.
</span>-A line of symmetry will connect a vertex and a midpoint of an opposite side
-it has 7-fold symmetry.
