Answer:
n(U) = n(AUB) + n(AUB)'
Step-by-step explanation:
The cardinality of the universal set will be to add the cardinalities of both the union of A and B i.e (A U B) and and the compliments of A and B i.e n(AUB)'
Answer:
Step-by-step explanation:
so we are looking for the x intercept (where the line crosses the x axis).
to do this, we sub in 0 for y and solve for x.
y = 1/2x + 4....sub in 0 for y
0 = 1/2x + 4
-1/2x = 4
x = 4 * -2
x = -8 <=== so it crosses the x axis at (-8,0)
Question 1:
(x*3)+18/8=9 is the equation
(x*3)+18=72 multiply by 8
(x*3)=54 Subtract 18
x=18 Divide by 3
The two digit number is 18
Question 2:
x*4=43 Divide by 4
x=10.75 10 3/4
10 3/4+3 3/4 Solve
14 1/2

your answer would be b becuase that is 3/6 so thats half and ou would simply it and 1/4 do the same
