Answer:
7) 1
8) -2
9) undefined (no slope)
10) 4/3
11) -2/7
12) 0
Step-by-step explanation:
to find the slope when given to points ... minus the y values and x values
formula :
y - y
------ = slope
x - x
Answer:
0.5 is the answer to this
Answer:
d = 4
Step-by-step explanation:
- 6 - d = 6 - 4d ( add 4d to both sides )
- 6 + 3d = 6 ( add 6 to both sides )
3d = 12 ( divide both sides by 3 )
d = 4
It is 10 times bigger. It is easy because you can do 50 x 10 which is 500 and you know it is 10 times bigger.
First you have to write down the formula on how to get the circumference of the circle (C = 2pi * Radius) and the Area of the circle which is (A=Pi*Radius^2). In getting the radius you need to transform the formula of the circumference by making the radius to be the unknown variable so it would become(R=C/2pi), after that you need to replace the radius in the formula of the area by the transformed formula of the circumference and you will come up of the formula of (A=Pi(C/2pi)^2).
