What are the discontinuities and zero of 5x/(x^2-25)? show your work.

  zero: x = 0

  discontinuities: x = -5, x = 5

Step-by-step explanation:

The zeros of the rational function will be found where the numerator is zero. That will happen when x=0.

__

There will be discontinuities where the denominator is zero. The denominator is the difference of squares, so factors as ...

  x^2 -25 = (x -5)(x +5)

These factors will be zero when x=5 and x=-5.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
