A: it is a decimal with a repeating digit of 5
4×+7y=-12 __ -4x-y=-12 ________ 0x+6y=-24 , so you eleminated by it self 6y/6=-24/6 , you get : y=-4 and then you plug in 4x+7(-4)=-12 , that's your answer 4x-28 =-12 , you divided in both side 4x=-12+28 , 4x=16 , and then x=16/4 =4 , so x=4
Yes it does because question back no remove
F(n) = 75*1/5n
This is because the base value would be 75 and it is divided by 5 each part of the sequence.
