Answer:
they're all rational numbers
Step-by-step explanation:
rational numbers are positive, negative, or zero integers. they can be decimals as well.
first expression = 2.449.... + 3 = 5.449 (yes, it is rational)
second expression = 8 + 0.54545454... = 8.545454... (yes, it is rational)
third expression = 6 + 4.582575... = 10.4582575... (yes, it is rational)
fourth expression = 4 + 13 = 17 (yes, it is rational)
fifth expression = 17.43... + 7 = 24.43.... (yes, it is rational)
sixth expression = 6.6332... + 5 = 11.6332 (yes, it is rational)

Step-by-step explanation:
Answer:
D. (x, y) → (-x, -y)
Step-by-step explanation:
A. (x,y) → (y,x) . . . . reflects across the line y=x
B. (x,y) → (y,-x) . . . . rotates 90° CCW
C. (x,y) → (-y,-x) . . . . reflects across the line y=-x
D. (x,y) → (-x,-y) . . . . rotates 180° about the origin
Learned this yesterday, lol.
It's basically just:
100[ (33-24)/24 ]
100[ 9/24 ]
100[ 0.375 ]
