false
They have opposite signs.
they are opposite signs
opposite of mean "negative" so the opposite of x is negative x or -x.
if the signs are the same you must add its opposite.
When x is not zero, it can be (x + 1/x).
No, it simply means that there is not a linear relationship between the variables. Try it with y = x2 with a set of x values which have opposite signs or 0 (eg 0, -x, x, -3x, 3x, -4x, 4x).
If by "opposite" you mean its additive inverse, the answer is 0. If by "opposite" you mean its multiplicative inverse, for the number x, it will be (x+1/x).
Negative. In its simplest form a single minus 1 is still minus 1. ie. (-1) x (+1) = -1
It depends on what is meant by "opposite". For the additive opposite: x = -x - 38 For the multiplicative opposite: x = 1/x - 38
additive inverses
It depends on the context. Since you posted this in the math section, then the answer is no. The inverse of x is 1/x, and the opposite of x is -x ■
