5x - y = -3......this is just a matter of subbing in ur answer choices to see which one makes the equation true.
5x - y = -3.....subbing in (-2,-7)...x = -2 and y = -7
5(-2) - (-7) = -3
-10 + 7 = -3
-3 = -3 (correct)
so ur answer is : B. (-2,-7) <==
Answer:
D. A cylinder is exactly 3 times bigger than a cone with the same height and radius. Therefore, the formula for the volume of a cone is 1/3 of the volume of a cylinder with the same height and radius.
Step-by-step explanation:
A cylinder and a cone with the same radius will have different volumes. This is because the cone comes to a point whereas the cylinder does not.
A filled cone will hold 1/3 of the amount of a cylinder with the same radius. This means that we can derive the formula for a cone by multiplying the formula for the volume of a cylinder by 1/3.
Answer:
B.
Step-by-step explanation:
Since 6 = 5r + 1, r = 1
As for s, if s is 2, then you can do
4 x 2 + 5 = 13 & 6 x 2 + 1 = 13
13 = 13
So B!
Hope that helps!
