The point (-2, -1) satisfies which of the following inequalities? 5x - 2y + 1 > 0 -5x + 2y + 1 > 0 -2x + 5y - 1 > 0 2x + 5y - 1 > 0

We can plug the given point in each equation and check if it satisfies it

1.

5x - 2y + 1 > 0

5(-2)-2(-1)+1>0

-10+2+1>0

-7>0 (false)

2.

-5x + 2y + 1 > 0

-5(-2) + 2(-1) + 1 > 0

10-2+1>0

9>0

so -5x + 2y + 1 > 0 satisfies the given point (-2,-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:

think about it deeply and passionately about this property
