Which is the intersection of the sets r= (0, 1, 2, 4), s= (4, 9, 12, 13), t= (13, 15, 19, 20)?

{ }     or    

Step-by-step explanation:

The intersection of sets is a set with all the elements the sets have in common.

R= (0, 1, 2, 4)

S= (4, 9, 12, 13)

T= (13, 15, 19, 20)

There is no element that ll sets have in common, so the intersection is the empty set.

R ∩ S ∩ T = ( )

Step-by-step explanation:

The intersection of the two sets A and B, which is represented by A∩B, is a set which contains all the common elements that belong to both set A and set B.

Here, we are given three sets:

R= (0, 1, 2, 4)

S= (4, 9, 12, 13)

T= (13, 15, 19, 20)

So we will look for the elements that are common in both the sets R, S and T.

However, we can see that there are no such elements which is present in all of the three sets. Therefore, the union of sets R, S and T will be a null set or empty set.

R ∩ S ∩ T = ( )

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
