Answer:

A. -¼(1+ 2y)

Step-by-step explanation:

-(½y + ¼) = -½y - ¼

-¼(1+ 2y) = -¼ - ½y = -½y - ¼

B is wrong. ¼(2y - 1) = ½y - ¼

C is wrong. -2(¼y - ⅛) = -½y + ¼

D. is wrong. 2(⅛ - ¼y) = ¼ - ½y = -½y + ¼

Answer:

202

Step-by-step explanation:

$in\\\\F(1)=4\:dots\\\\F(2)=F(1)+2=4+2=6\:dots\\\\F(3)=F(2)+2=F(1)+2+2=F(1)+2(2)=8\:dots\\\\As\:you\:can\:see\:in\\\\F(n)=F(1)+2(n-1)\\\\So\:with\:n=100\\\\F(100)=F(1)+2(100-1)\\\\F(100)=4+2(100)+2(-1)\\\\F(100)=4+200-2\\\\F(100)=200+2\\\\F(100)=202$
