Question 550103: If a < b, then | a - b | is equivalent to which of the following?
my act answer key had k as the answer but i don't how it got that, so with a good explanation by showing work would be much appreciated. thanks for ur help!
f. a+b
g. -(a+b)
h. square root of a-b
j. a-b
k. -(a-b) Answer by mathstutor458(57) (Show Source):
You can put this solution on YOUR website! modulus (||symbol) value should not negative
the condition is a
we know that |x|= plus or minus x
so |a-b|=a-b or -(a-b)
but here if we take |a-b|=a-b = -ve value(from the above condition)
so here we have to take |a-b|=-(a-b) which gives positive value
