Three vertices of parallelogram PQRS are p (-3,-2), q(1, -5) and r (9,1) with p and r diagonally opposite. The sum of the coordinates of vertex s is: A. 13
B. 12
C.11
D.10
E.9

5.25 ounces

step-by-step explanation:

divided 3/4 and 6

(3x-8) or (3x+8)

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
