The negative reciprocal of a non-zero number x, is -1/x.
And the negative reciprocal of that is -1/(-1/x) = -1*(x/-1) = x

What are mathematical operations that undo each other called?
Inverse operations, or reciprocals.
When are two reciprocals opposite of each other?
Always. That is what a reciprocal is. in other words, if x = 1/y then y = 1/x
How do you figure out negative exponents?
They are the reciprocals of the positive exponents. Thus, x-a = 1/xa
What do pairs of numbers whose product is 1 called?
They are called multiplicative inverses or reciprocals of each other.
What can you say about the slopes of two non-vertical perpendicular lines?
They are negative reciprocals Ex -1/2 and 2
Do parallel lines have negative reciprocals?
The slope of parallel lines are the same, but the slope of perpendicular lines are negative reciprocals of each other.
Lines that are perpindicular have slopes that are?
negative reciprocals of each other
What are two numbers that are blank if their product is negative 1?
The numbers are negative reciprocals of each other.
What does it mean if two line segments are perpendicular to each other?
their slopes are negative reciprocals of each other. and they make a right angle when they intersect.
If two lines have slopes that are negative reciprocals of each other then they are if they have slopes that are the same then they are?
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
If two lines are perpendicular?
one slope is the negative reciprocal of the other
Line that have Slopes that have negative reciprocals are ---- to each other?
Those lines are perpendicular.Those lines are perpendicular.Those lines are perpendicular.Those lines are perpendicular.
If two lines are their slopes are negative reciprocals?
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.
If two numbers are opposite of each other are their reciprocals also opposite of each other?
i think it is
What are mathematical operations that undo each other called?
Inverse operations, or reciprocals.
How do frequency and period relate to each other?
Frequency and period are mutual reciprocals.
What is the definition of a slope of parallel lines?
Horizontal lines have a slope of zero, and the slope of vertical lines is undefined. Parallel lines have equal slopes, and perpendicular lines have slopes that are negative reciprocals of each other. So we can say that: Two nonvertical lines are parallel if and only if they have the same slope. Two lines are perpendicular if and only if their slopes are negative reciprocals of each other. That is, if the slopes are m1 and m2, then: m1 = - 1/m2 or (m1)(m2) = -1
