Answer:
The pre-image of the quadrilateral is attached.
Step-by-step explanation:
Each point (x, y) is rotated with the rule (x, y) -> (-x, -y).
So, point W'(2, 3) was W(-2, -3) before rotation.
X'(6, 3) was X(-6, -3)
Y'(6, 4) was Y(-6, -4).
Z'(3, 5) was Z(-3, -5).
The pre-image of the quadrilateral is attached.
Answer:
<u>The original cost of the printer before adding the tax was $ 173.98</u>
Step-by-step explanation:
Total cost of the color printer, including tax = $ 186.16
Tax rate = 7%
Original cost of the printer, before tax = x
For answering the question, let's use the Rule of Three Simple, this way:
Percentage Value
107% 186.16
100% x
x * 107 = 186.16 * 100
107x = 18,616
x = 18,616/107
x = 173.98
<u>The original cost of the printer before adding the tax was $ 173.98</u>

<u>Answer:</u>
<u>Step-by-step explanation:</u>
We are to find the equation for the line which is perpendicular to another line with the equation 
and passes through a point (2, 10).
Since the slope of a line which is perpendicular to another line is the negative reciprocal of the other line, therefore the slope of our line will be 
.
Finding the y-intercept:
Therefore, the equation of the line will be .
