Is (0,0) a solution to this system y> =x^2+x-4; y< =x^2+2x+1

yes it is a solution

Step-by-step explanation:

o>-4

0<1

yes both work out to be equal

It is a solution

Step-by-step explanation:

Check and see if (0,0) satisfies both inequalities.

The first inequality is:

When we put x=0, and y=0, we get:

This part is true.

The second inequality is:

We put x=0 and y=0 to get:

This part is also true.

Since the (0,0) not satisfy both, inequalities, it is a solution.

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:

something over 10 so ? /10
