A periodic function has minimum values at -1 and maximum values at 10. What is its amplitude?

8121 because

130,000 divided by 16 is 8121

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

15 units use socratic

step-by-step explanation: 15 units

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
