Answer:
Step-by-step explanation:
labor cost = 20 * h = 20h
Total cost = 100 + 20h
<em>P'(3,-7) Q'(7,6) R'(-8,-7).</em>
<u>Reflection across the x-axis</u>
Given a point P(x,y), its reflection across the x-axis will map to point P'(x,-y), i.e., the y-coordinate gets inverted.
We are given the vertices of a triangle P(3,7) Q(7,-6) R(-8,7). The vertices of the image reflected across the x-axis are:
P'(3,-7) Q'(7,6) R'(-8,-7).
The new triangle has vertices P'Q'R'.
iIm sorry dont report but i do not understand what im answering, but ill take the points thank you
a)
_b+_=_
6B+3=75
B)
He ordered 12 books
so each book (b) costs $6. he payed $75 total including the $3 shipping price
That gets us:
6b+3=75
6b=72
b=12
Therefore, Tom ordered 12 books
