Answer:
- rotate CCW 90°, reflect across the x-axis
- (x, y) ⇒ (-y, -x) . . . . . both transformations together
Step-by-step explanation:
The vertex order ABC is clockwise in the original figure and also in the first image: A'B'C'. The altitude from AC to B is up in the original and left in the first image, indicating a rotation 90° CCW.
The first transformation is a rotation 90° CCW.
The vertex order of A''B''C'' is CCW, indicating a reflection. The direction of the altitude from A''C'' to B'' is still to the left, so the reflection must be over a horizontal line. We find the x-axis bisects the segments A'A'', B'B'', and C'C'', confirming that it is the line of reflection.
The second transformation is reflection across the x-axis.
_____
Algebraically, the transformations are ...
1st: (x, y) ⇒ (-y, x)
2nd: (x, y) ⇒ (x, -y)
Both together: (x, y) ⇒ (-y, -x).
<span>106% of $ _______ = $7.95
this means that 1.06 of the price of the cooler is 7.95
so we can assume th
</span>at the cooler price is x
then:
1.06 x = 7.95
Divide both sides by 1.06, we get:
x = 7.5
The price of the cooler itself without tax is $7.5
----.----.----
to check you answer:
7.5 + 7.5*6%= 7.5 + 7.5*0.06 = 7.5 + 0.45 = 7.95$
Correct!! :)
