The sets a and b are shown below
a= (0,5,10,15)
b=(-4,-2,0,2,10)
find the union of a and b

The union of the sets is {-4,-2,0,2,5,10,15}.

The intersection of the sets is {0,10}.

Step-by-step explanation:

means the list elements that you see in either set:

{-4,-2,0,2,5,10,15}.

Notice I didn't list any element twice for occurring in both sets.

means the elements that occur in both set or the elements you see in common between the two if you prefer this wording of the definition:

{0,10}.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
