If a = {1,3,5} and b= {1,2,3,4,5,6} then a u b

Hello from MrBillDoesMath!

A U B = B

Discussion:

A U B = { set of all x in A or B or both}

so

A U B = {1, 2, 3, 4, 5, 6}

or

A U B = B

Note that the values, 1,3,5 (from A) are NOT included twice in the union.

Thank you,

MrB

what is the original number? you forgot to add it.

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

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
