Answer:
x ≠ 3
Step-by-step explanation:
In any case, the domain is restricted to values of the variable for which the function is defined. The value 1/0 is not defined, so the variable cannot allow the denominator to be zero. The denominator x-3 will be zero for x=3, so that value of the variable cannot be in the domain.
The domain is all real numbers except x=3.

<em>Additional comments</em>
It is useful to become familiar with the domains of different functions. As we saw above, the reciprocal of 0 is undefined. The square root of a negative number is undefined. The log of a non-positive number is undefined. Trig functions are defined everywhere, but their inverse functions are not. Polynomial functions are defined everywhere, but ratios of polynomials have the same restriction on denominators that we see above.
12a+9b=k (2a+3/2b)
Which value of k makes the equation true?
1) 6
118 × 3 = 354 feet ( Path A)
180 × 3 = 540 feet ( Path B)
Path B as it is closer to 500 feet than path A
➨ Let (x+2) = a ➩ 
Then we factor a-term out of the expression ➩ Common Factor ➩ 
Then convert from a back to x+2
Thus, our answer would be ➩ 
Answer:
2 5/8 inches
Step-by-step explanation:
This is a subtraction problem.
You must subtract 58 1/8 inches from 60 3/4 inches.
We need a common denominator for the fractions.
The LCD of 4 and 8 is 8.
60 3/4 = 60 6/8
58 1/8 = 58 1/8
60 3/4 - 58 1/8 = 60 6/8 - 58 1/8 = 2 5/8
Answer: 2 5/8 inches
