What are the two requirements that must be met for a transformation to be rigid motion

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

idk

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
