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).
4 * 500 = $2,000
<span>Then, you must calculate how much he earned by the commission: </span>
<span>$42,000 * 3% </span>
<span>(3% = 3/100) </span>
<span>42,000 * 3/100 = 420 * 3 = $1260 </span>
<span>Finally, you add what he earned form the commission plus the 4 weeks salary: </span>
<span>$2,000 + $1260 = $3,260</span>
If your solving for B then its B<43/3
Answer:
The answer is A.
