Answer:
The lines are perpendicular
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are equal
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
we have
----> equation A
isolate the variable y
Divide by 7 both sides
The slope of the line A is
----> equation B
isolate the variable y
Divide by 3 both sides
The slope of the line B is
Compare the slope of both lines
so
----> the lines are not parallel
Find the product of the slopes
----> the lines are perpendicular
The correct order of the radius .
What is decreasing and increasing order?
A set of data is said to be in descending order, often referred to as decreasing order, when it is arranged from highest to lowest or largest to smallest.
The same concepts apply regardless of the type of information you're working with, whether it's letters, dates, sizes of things or any other group of information like numbers or dates.
For instance, arranging a group of numbers in descending order means doing so from biggest to smallest value.
Ascending order, often known as ascending order of importance, is the exact opposite of declining order.
The order of the items is lowest to highest value. The lowest value is placed first in the order, while the highest value is placed last.
The value of = 1.732
so / 11 = 1.732/11
=1732/11000
The value of = 3.14
so / 24 = 3.14/24
= 314/2400
