The word "sum" means that we have to add.
3/4 + 18/19 (least common denominator= 76)
= 57/76+ 72/76
= 129/76
= 1 53/76.
The sum of 3/4 and 18/19 is 1 53/76~

Answer:
x=0, y=1.
Step-by-step explanation:
-8x+12y= 12
-2x-12y= -12 Adding these 2 equations:
-10x = 0
x = 0.
Plug this into equation 1:
-8(0) + 12y = 12
12y = 12
y = 1.
f(x) = sqrt [( x - 3) / (x - 5)]
well x cannot be 5 because that would make x - 5 = 0.
Also the fraction x - 3 / x - 5 cannot be negative because theres no real square root of a negative.
So x must be <= 3 or > 5
In interval notation the domain is ( -∞,3] or (5 , ∞)
