What is the graph of the function f(x) = negative x squared minus 9 x minus 20 all over x plus 4?
c.
a line that crosses through the x axis at negative 5 and the y axis at negative 5. a discontinuity exists at 4 comma negative 9.
d.
a line that crosses through the x axis at negative 5 and the y axis at negative 5. a discontinuity exists at negative 4 comma negative 1.

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:

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.
