Answer:
Step-by-step explanation:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. y=6 is a straight line perpendicular to the y-axis at point (0,6) , which means that the range is a set of one value {6} .

Step-by-step explanation:
2(x-2) - 3(x-4)
Simplify:
2(x-2)-3(x-4)
2x-4-3(x-4)
Distribute:
2x-4-3(x-4)
2x-4-3x+12
Add the numbers:
2x-4-3x+12
2x+8-3x
Combine like terms:
2x+8-3x
-x+8
Hence Solution = -x+8
Answer:
Proportional relationships are relationships between two variables where their ratios are equivalent.
Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
I really recommend watching Khan Academy's video over proportional relationships, the speaker explains it very well!!
