Write the equation of the line that is perpendicular to the line 2x - 3y=5 and that
passes through the point (2, - 1).

3x + 2y = 4

Step-by-step explanation:

2x - 3y = 5

3y = 2x - 5

y = 2/3 x - 5/3     m1 = 2/3

m2 (slope) for perpendicular line: - 3/2

b (y intercept) = y - m x = -1 - (-3/2) * 2 = 2

equation: y = mx + b

y = (-3/2) x + 2

3x + 2y = 4

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:
