Answer:
E (3,-1)   D (-2, -2)   G (-1, 3)    F (3, 2)
Step-by-step explanation:
90 degrees = (y, -x)
that means you take the ordered pair you want to rotate and plug the x and y into the new spots.  
for example, point E is at (1,3) so the point rotated 90 degrees is (3,-1)

X=-8 is your answer for this problem
        
             
        
        
        
Convert the grams into milligrams. 0.5 = 500 (to covert you'll multiply .5  x 1000).
D/H x Q will be the formula to use now that we have like terms (mg).
D= dose to give
H = dose that is supplied
Q= quantity to give
In this case your numbers will be 
D = 500mg
H = 250mg
Q = 1 tablet
500 ÷ 250 = 2 
2 x 1 = 2
 So, that means you will give 2 tablets to your patient.
