Answer:

117 bags

Step-by-step explanation:

First day number of bags used by Raul=  3 bags

  We have to calculate the number of bags next three following days

On second day, number of bags used by Raul= 3×3=9

similarly, on third day number of bags used by Raul= 9×3=27

similarly, on fourth day number of bags used by Raul= 27×3=81

 Hence, the total number of bags used by Raul= 9+27+81=117

Hence, the correct answer is 117

Step-by-step explanation:

One solution:  when two lines intersect in exactly one point.

Infinitely many solutions:  When one of two lines can be shown algebraically to be exactly the same as the other.  The two lines coincide.

No solution:  The two lines have the same slope but different y -intercepts.  They can't and don't intersect.

How are the functions f(x)=16x and g(x)=16 1/2x related? The output values of g(x) are one-half the output values of f(x) for th
KATRIN_1 [288]
If your functions are
  f(x) = 16·x
  g(x) = 16·(1/2x)
The output values of g(x) are one-half the output values of f(x) for the same value of x.

If your functions are
  f(x) = 16^x
  g(x) = 16^(1/2x)
The output vaules of g(x) are the square root of the output values of f(x) for the same value of x.

You seem to have left out the relevant operator symbol, so we don't really know your intent. Copy/paste operations will do that. Editing is sometimes needed.
