Which expression is equivalent to the given expression?
-(1/2y + 1/4)

a. -1/4 (1 + 2y)

b. 1/4(2y - 1)

c. -2 (1/4y - 1/8)

d. 2 (1/8 - 1/4y)

homozygous. one is homozygous, while two is heterozygous.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
