Let A = {a, b, c, d, e} and B = {a, c, f, g, i}. Universal Set: ∪= {a,b,c,d,e,f,g,h,i}

Answer:
1. { a, b, c, d, e, h }
2. { f, g, i }
Step-by-step explanation:
Given sets,
A = {a, b, c, d, e},
B = {a, c, f, g, i}
Universal set , ∪ = {a, b, c, d, e, f, g, h, i},
1. Since, 
= elements of universal set which are not in set B
= U - B
= { b, d, e, h },
Thus,
= All elements of A and
= { a, b, c, d, e, h }
2. B - A = elements of set B which are not in set A
= { f, g, i }
L = pounds of lollipop
c = pounds of caramel candies
0.95l + 1.10c = 30 ($0.95/lb & $1.10/lb)
l + c = 30 (mixture sells for $1/lb)
c = 30 - l
0.95l + 1.10(30 - l) = 30 (Substitution)
0.95l + 33 - 1.10l = 30
-0.15l = -3 (move terms)
l = 20lbs
Hope this helps.
Do you mean 45x95x-12? If so the answer is -51300

1. x = -5/2
y = 100
25x +10y = 1000 a. Subtract 25x from both sides
-25x -25x
10y = -25x +1000 b. Divide both sides by 10
÷10 <span>÷10
y = -5/2x +100
2. x = -2/5
y = +7
m = slope x= = slope therefore m = x
When it asks for y, it's referring to the y-intercept (expressed as b)
