Which statement best describes the graph of f(x)=-x^4+3x^3+10x^2

The graph touches the x-axis at x=0 and crosses the x-axis at x=5 and x=-2.

Step-by-step explanation:

We are given the following function:

We know that the function crosses the x-axis when y = 0 so we will put this function equal to zero and solve it.

Taking the common out:

Therefore, the graph touches the x-axis at x=0 and crosses the x-axis at x=5 and x=-2.

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:
