Write an equation of a line in point-slope form that passes through the point (-2,4) and is perpendicular to the line y = -2x - 4. A. y - 2 = 2 (x – 4)
B. y+2 = ] ( 2 – 4)
C. y - 4= 2 (2+2)
D. y– 4= } (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:

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

m∠a is 90°

m∠b is 40°
