33+9=42. 42-40=2. These simple calculations show that two people must have raised there hands for both because the sum of the two groups who raised hands is two more than the amount of people in the actual class
Answer:
y=x, x-axis, y=x, y-axis
Explanation:
Reflecting the figure across three axes just moves it from one quadrant to another. It does not map the figure to itself.
Reflecting across the line y=x moves it from quadrant II to IV or vice-versa. If it is in quadrant I or III, it stays there. So the sequence of reflections x-axis (moves from I to IV), y=x (moves from IV to II), x-axis (moves from II to III), y=x (stays in III) will not map the figure to itself.
However, the last selection will map the figure to itself. The initial (and final) figure location, and the intermediate reflections are shown in the attached. The figure starts and ends as blue, is reflected across y=x to green, across x-axis to orange, across y=x to red, and finally across y-axis to blue again.
Draw a picture if you are a visual person if not then just do 22 divided by 2 and I got 11hrs
50 miles. 15 is to 30 as 50 is to 100.
