Substitute x + 1 as x in the equation of the function:

Used

You can set y = to each side of the equation, then multiply by the denominator and put into standard form.
Left side:
.. y = 1/4x -3
.. 4y = x -12 . . . . multiply by 4
.. 4y -x = -12 . . . subtract x
Right side:
.. y = 1/2x +8
.. 2y = x +16 . . . multiply by 2
.. 2y -x = 16 . . . subtract x
These equations correspond to selection B.
Answer:
Domain is the whole R and the range is R+. The domain is continuous
Answer:
x = 3 + y
Step-by-step explanation:
4x - 2y = 6
~Add 2y to both sides
2x = 6 + 2y
~Divide 2 to everything
x = 3 + y
Best of Luck!
I'm pretty sure its 80, if this isnt for school i suggest Calculator Soup's LCM calculator (:
