R= {2,5,3} Domain is the x values and Range is the y values.
Slope is 12/6=2
y+6=2(x+4)
y=2x-2
Given:
The minimum and maximum distance that the dog may be from the house can be found by using the equation:

To find:
The minimum and maximum distance that the dog may be from the house.
Solution:
We have,

It can be written as:

Adding 500 on both sides, we get

Now,
and 
and 
The minimum distance is 492 meters and the maximum distance is 508 meters.
Therefore, the correct option is C.

in simplest form would be

because you could divideboth numerator and denominator by 2. Hope it helps!!
Hello from MrBillDoesMath!
Answer:
15
Discussion:
Given: measure angle STQ = 7x + 55. But, as shown, STQ is a right angle so
7x + 55 = 90 => subtract 55 from each side
7x = 90 -55 = 35 => divide each side by 7
x = 35/7 = 5
Since RS = (x+1) + (2x-1) where x = 5.
RS = (5 + 1) + (2*5 -1)
= 6 + 9
= 15
I don't know what choice the answer is as your diagram only shows Choice A
Thank you,
