Answer:
Step-by-step explanation:
12/25 =
12 ÷ 25 =
0.48 =
0.48 × 100/100 =
0.48 × 100% =
(0.48 × 100)% =
48%;
24 1/2. 0.5 is equal to 1/2
If the traslation is T(x,y)=(x-1,y+1) then:

Therefore A'=( -7,3).
So we have the equations:
y - 4x = 2 --- equation 1
5y - 2x = 1 --- equation 2
(equation 2) * 2
10y - 4x = 2 --- equation 3
(equation 2) - (equation 3)
-9y = 0 so y= 0 and thus x = -1/2
Hope that helps!
