tolong banget jangan asal please bantu aku please!!!!!!!!!​

Answer 1

TRansFor Geo
Rotasi [O, 45°]

x'=  ¹/₂√2 x - ¹/₂√2 y
y'= ¹/₂√2 x  + ¹/₂√2 y

P(4, -6)  R[ O, 45⁰]
x'=  ¹/₂√2 (4) - ¹/₂√2(-6)
x' =  2√2 +  3√2
x'= 5√2

y'  = ¹/₂√2x +  ¹/₂√2 y
y'=  ¹/₂√2 (4) + ¹/₂√2( -6)
y'=  2√2 -  3√2
y'=  - √2

bayangan P {x', y'} =
P' = {5√2 , - √2}
