F and H are sets of real numbers defined as follows.

F={w | w>3}

H={w | w>6}

Write FUH and Fn H using interval notation.

If the set is empty, write Ø.

Step-by-step explanation:

Given the sets F and H of real numbers defined as given:

F={w | w>3}

H={w | w>6}

To write a set in interval  notation, we use these brackets, (  ) for < or > while we use [ or ] for .

Since our sets are defined by strict inequalities(< or >)

In interval notation

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
