Answer:g(x) = (x+3)/(x2-4)
The domain refers to all of the x values that the function can take on. In a rational expression like the one above, we have to be careful that the denominator is never 0, since division by 0 is undefined. We can factor the denominator of g(x) as follows:
g(x) = (x+3)/((x+2)(x-2)
The denominator will be zero when x = 2 or -2. Otherwise, g(x) is defined on all other values of x. So the domain of g(x) is "x = all x not equal to -2 or 2". In interval notation, the domain is:
(-∞,-2)U(-2,2)U(2,+∞)
On a number line, draw it as follows:
-∞ <======o=====o=======> +∞
-2 2
Step-by-step explanation:
The fat percentage in the second type(40 liters) of milk is 1%
<h3>Percentage</h3>
- fats in 80 liters milk = 2% fat
- 40 liters = x % fat
- Total fat = 3%
Fats in 40 liters of milk = Total fat - fats in 80 litrrs milk
= 3% - 2%
= 1%
Therefore, the fat percentage in the second type of milk is 1%

Answer:
X=10
Step-by-step explanation:
x+10-10=2x-10
x=2x-10
x-2x=2x-10-2x
-x= -10
-x/-1= -10/-1
x=10
