Answer:
Step-by-step explanation:
20/25=4/5
21/49=3/7
66/88=3/4
27/45=3/5
I actually don't know tttttttttttþyyyyyyyyyttyyytrreeeee
Divide 7 into 42 your answer would be 6 then add 7 and get '13
(x , y ) ---> (x + 6 , y - 3)
P(-1 , 4) -----> P'(-1+6 , 4-3) = P'(5,1)
Comapre P and P' x-coordinate
-1 + a = 5
a = 5 +1 = 6
Q(-1, 2) ----->Q'(-1+6 , 2 -3)= Q'(5, -1)
R(3 , 1) ------> R'(3+6 , 1-3) = R'(9,-2)
x=18
3(x-4)=2x+6
3x-12=2x+6
3x-2x=6+12
