Answer:
omigosh hope she gets better i will look at the pdf and solve
Step-by-step explanation:
okay so for most of them you can just multiply by the denominator to turn it into a regular number (to get it out of fraction form) and then use basic algebra to solve for x. I 'll write the answers to problems 1-9 in the comments
Answer:
- 1
Step-by-step explanation:
Let the slope of one line be 's' , then according to the given condition that the slope of second line is negative reciprocal of the first , We obtain the slope of the second line as 
.
So, the product of both the slopes is given by 
This shows that whatever the slopes may be if they are negative reciprocal of each other then their product will always be -1
It is rational. Any number that can be described as a fraction is rational while those that do not are irrational.
-0.28764 is the same as -(28764/100000) and positive, negative does not matter.
