Answer:
x = -30
Step-by-step explanation:
subtract 7 from both sides ( 7+2/5x -7, -5-7 )
simplify ( 2/5x = 12 )
multiply both sides by 5 ( 2/5x times 5 = 5 (-12) )
simplify ( 2x = -60 )
divide both sides by 2 ( 2x / 2, -60 / 2 )
x = -30
The answer to this is ten.
Hello,
The translation t is (x,y)->(x-2,y+3)
So its inverse t^(-1)=-t is (x,y)->(x+2,y-3)
B=-t(B')=(4+2,-8-3)=(6,-11)
