Answer:
3
Step-by-step explanation:
Cardinalities are the number of elements in a set.
(A∩B∩C) is the very middle part of the circle, and there are 3 elements there.
Answer:
x = 63 , y = 27
Step-by-step explanation:
x+ 117 make a straight line so they equal 180 degrees.
x+117 = 180
Subtract 117 from each side
x+117-117= 180-117
x =63
x and y are complementary, which means they add to 90
x+y = 90
63+y = 90
Subtract 63 from each side
63-63+y = 90-63
y = 27
Hello:<span>
equation is the line is : y = ax+b
a is a slope
y = (-3/4)x+b
passing through the point (5/3;−7) : -7=(-3/4)(5/3)+b......b =-23/4
y = (-3/4)x-(23/4)</span>
A perpendicular equation to another equation has a slope that is the negative reciprocal of the slope of the equation. The negative reciprocal of -1/4 is 4, so the slope of the new line is 4. Our equation so far is y=4x+b. Then, since we know that it goes through the point (-4,3), we can substitute their values into the equation. This gives us a value of b of 19. This gives us the equation y=4x+19.
