Under a counterclockwise rotation about the origin of 90°
a point (x , y ) → (- y, x ), hence
A(2, 1 ) → A'(- 1, 2 )
Assuming we are solving for t
2<-1t

Answer:
4.57
Step-by-step explanation:
7 can go into 32 4 times but your remainder is going to be 5
1.7a + 0.3a = 0.8;
(1.7 + 0.3)a = 0.8;
2 x a = 0.8;
a = 0.8 ÷2;
a = 0.4;
