Answer:
Option D. 
Step-by-step explanation:
Let
v------> the volume of a full bottle of Jun's favorite hot sauce, in milliliters
we know that
Using proportion
10/100 = x / (810+x)
1/10 = x / (810 + x)
10x = 810 + x
9x = 810
x = 90 g salt
mass of solution = mass of water + mass of salt
ms = mw + m salt
ms = 810 + 90
ms = 900 g of solution
All of these transformations are equivalent to reflection across the line y=x:
- a reflection across the y-axis followed by a clockwise rotation 90° about the origin
- a clockwise rotation 90° about the origin followed by a reflection across the x-axis
- a counter-clockwise rotation 90° about the origin followed by a reflection across the y-axis
- a reflection across the x-axis followed by a counter-clockwise rotation 90° about the origin
_____
These are all but the second choice.
... reflection across y: (x, y) ⇒ (-x, y); 90°CW: (-x, y) ⇒ (y, x)
... 90°CW: (x, y) ⇒ (y, -x); reflection across x: (y, -x) ⇒ (y, x)
... 90°CCW: (x, y) ⇒ (-y, x); reflection across y: (-y, x) ⇒ (y, x)
... reflection across x: (x, y) ⇒ (x, -y); 90°CCW: (x, -y) ⇒ (y, x)
Note that the second choice gives a different result:
... reflection across y: (x, y) ⇒ (-x, y); 90°CCW: (-x, y) ⇒ (-y, -x)
It would be the last answer because as you can see the line goes up for 2 hours and then goes straight for 1 hour than goes up again for 2. -The last option
