Answer:
C
Step-by-step explanation:
the domain is the set of numbers that can be x values. in this case, the equation is linear so any number you plug in for x will give you a y value
Answer:
x = 2 and x = -2
Step-by-step explanation:
The easiest way is to guess. We know that you can't have a square root of a negative number. This constrains x between negative infinity to 2. Testing 2 and -2, we see that it satisfy the equation.
The more systematic approach is shown below


x= -2, 2
Answer: 
Step-by-step explanation:
Cross multiply the fractions to get the following equation:
3w = 4*6
3w = 24
Divide both sides by 3 to get w by itself.
w = 8
The answer is w = 8.
