Answer:
y = -4/3x + 2
Step-by-step explanation:
to find slope use m= y2-y1/x2-x1
m= 3-(-1)/-6-(-3)
m= 4/-3
m= -4/3
then use point slope formula (y-y1) =m(x-x1)
(y-(-1)) = -4/3(x-(-3))
simplify
y+1 = -4/3x + 3
turn into slope intercept form
y = -4/3x + 2
the number of elements in the union of the A sets is:5(30)−rAwhere r is the number of repeats.Likewise the number of elements in the B sets is:3n−rB
Each element in the union (in S) is repeated 10 times in A, which means if x was the real number of elements in A (not counting repeats) then 9 out of those 10 should be thrown away, or 9x. Likewise on the B side, 8x of those elements should be thrown away. so now we have:150−9x=3n−8x⟺150−x=3n⟺50−x3=n
Now, to figure out what x is, we need to use the fact that the union of a group of sets contains every member of each set. if every element in S is repeated 10 times, that means every element in the union of the A's is repeated 10 times. This means that:150 /10=15is the number of elements in the the A's without repeats counted (same for the Bs as well).So now we have:50−15 /3=n⟺n=45
Answer:
4/6 and 6/15
Step-by-step explanation:
simplify all fractions to lowest possible.
4/6 = 2/3
10/25 = 2/5
6/15 = 2/3
4/6 and 6/15 are equivalent
