Set X = {x|x is a whole number less than or equal to 10} and set Y = {/15, 10, 15, 20} a. What is X Y ?
b. What is X UY ?
A
a.
X Y = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20}
b. XUY = {5, 10}
B. a X Y = {5, 10, 15, 20}
b. XUY= 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20}
C. a. X Y = {5, 10}
b. XUY = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20}
OD. a X Y = {0,1,2,3,4,5,6, 7, 8, 9, 10, 15. 20}
b. X Y = {5,10,15, 20}

C

Step-by-step explanation:

The first part requires the intersection of the two sets, which means only the elements that can be found in both sets.

While the second part requires all the elements in both the sets.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
