This differs on what number you want to talk about. 1 is the hundreds, 8 is the tenths, 7 is the ones.
Answer: 63.7 + (-26) = 37.7
The value of Ry= -x (P) is P' = (4, 6)
<h3>How to determine the transformation?</h3>
The point is given as:
P = (-6, 4)
The transformation Ry= -x (P) means tha:
(x, y) = (y, -x)
So, we have:
P' = (4, 6)
Hence, the value of Ry= -x (P) is P' = (4, 6)

Answer: 2((x+y)-21)
Calculation/Explanation:
Twice the sum of x and y decreased by 21 means that you must add x and y first before decreasing by 21. The last step is to double the whole equation that we just performed.
