y – y1 = m(x – x1)
First, you have to find m, or the slope.
This is
y - y
-------
x - x
It doesn't matter which way you put it in, but I'm going to do it like this:
-10 - (-8)
-------------
-7 - (-6)
This reduces into:
-2/-1 = 2
Now, it'll look like this (according to your answer choices, but you can use the other coordinate, also):
y - (-10) = 2(x - (-7))
This turns into:
y + 10 = 2(x + 7)
This answer is: C.
Answer:
20-16
=4
4/16*100
=25%
Step-by-step explanation:
It would be equal to 330/100 in fraction form
so, your answer is 330/100
If the carpenters blade is 1/8 inch you need to subtract the amount of the blade, so you subtract 1/8 three times from the total amount of wood. You should get 25/8 or 3 1/8. You will then divide that answer by four because, there will be four boards left at the end of the cutting. The quotient you should find will be 25/32, so that is the answer.
