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.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
