Answer:
Step-by-step explanation:
Interchange x and y: (-6, 8) is the image of (8, -6) after a reflection over y = x.
When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together.
7^(-1) x 7^(-7) = 7^(-8)
When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1.
7^(-8) / 7^(-7) = 7^(-1)
So your answer would be 7^(-1).
Hopefully my explanation was clear?
Answer:
Option A is correct.
The value of r = -0.7 represents the strongest negative correlation.
Step-by-step explanation:
A correlation is a value that describes a relationship between two things or variables.
Strongest Negative Correlation says that closer a negative correlation to -1, the stronger the relationship between the two variables.
From the options, we have only two negative values i.e, r= -0.7 and r= -0.22.
We have to find the strongest negative correlation r-value.
By the definition, you can see that -0.7 is very closer to -1 ,
therefore, the value of r = -0.7 represents the strongest negative correlation.
In this case since 067 is less than 180, 180 will be added to it to find the bearing of b from a.
067+180=247
the bearing of b from a is 247
or
subtract 067 from 360
360-067=293
I am not sure of the right answer but I hope this helps.
Answer:
Step-by-step explanation:
Answer for #5
Two Points M(-7,1) and N(5,1).
1. Formula is 
2. Let’s say (x1,y1) = (-7,1) and (x2,y2) =(5,1)
3. Distance = 
so distance between two warehouses is 12 miles
Answer #6
In the question it is saying the “Distance between two stores is half the distance between warehouses“ so it is 
= 6 miles
Answer #7
S1(-4,1) and distance of S1 and M is 3 Miles.
Answer #8
S2(2,1) and distance of S2 and M is 3 miles.
