Q: What is the least they could weigh together?
A: 0.62 kg
=================================================
Work Shown:
x = weight of first ball
y = weight of second ball
each ball has a weight range of 0.31 kg to 0.37 kg, so,

add straight down to get

which simplifies to

the two soccer balls have a weight range of 0.62 to 0.74, inclusive of both endpoints.
--------
Without using algebra, you basically just add the smallest the two weights could be (0.31) to itself to get 0.31+0.31 = 0.62 which represents the smallest the two weights combined can be. The same happens with the largest weight of 0.37 to get 0.37+0.37 = 0.74 as the max weight of both objects together.
Y= -2(x²-x)+2= -2(x-1/2)²+2+1/2= -2(x-1/2)²+5/2
<span>x=6, y= -2(11/2)²+5/2= -121/2+5/2= -58
