Answer:
Step-by-step explanation:
first find the slope
m = Δy/Δx = (-1 - (- 5)) / (4 - (-2)) = 4/6 = 2/3
Then plug either point into the equation
y - y₁ = m(x - x₁)
y + 1 = 2/3(x - 4)
which is equivalent to
y + 5 = 2/3(x + 2)
Answer: c
Step-by-step explanation:
4a^2-2ab-5b^2 :) that is simplified
4 = - 3(2) + c
4 = - 6 + c
c = 10
y = - 3x + 10
Answer:
24 cubic inches
Step-by-step explanation:
The formulas for the volume of a cylinder and cone are ...
volume of a cylinder = πr^2·h
volume of a cone = (1/3)πr^2·h
For the same radius and height, the cone has 1/3 the volume of the cylinder. Your cone's volume is ...
(1/3)·(72 cubic inches) = 24 cubic inches
