Answer:
(x , 1/2x - 5/2) where x is a real number.
Step-by-step explanation:
-2x + 4y = -10 ⇔ 4y = 2x - 10 ⇔ y = 1/2x - 5/2
then any couple of the form (x , 1/2x - 5/2) is a solution to the equation
example :
let x = 7 then 1/2x - 5/2 = 1/2(7) - 5/2 = 1
in this case -2x + 4y = -2(7) + 4(1) = -14 + 4 = -10
then (7,1) verify the equation
(a) \-1,\ (b) \9
(c) \-24 if 8m not wrong thats the answer
Answer:
box X with 126 sq. cm. i hope this helps :)
Step-by-step explanation:
okay so we have box X which is 6 * 3 * 7 = 126
then we have box Y which is 11 * 2 * 5 = 110
so box X will hold more
