Answer:

A(2/9, 1/3)

B(2/3, -1/3)

slope = -1.5

Step-by-step explanation:

A graph can show the coordinates of interest: A(2/9, 1/3); B(2/3, -1/3).

Rearranging the equation to slope-intercept form, we have ...

3y = -4.5x +2

y = -1.5x +2/3

The slope is -1.5.

How can we find the volume of a cone? explain in brief .

densk [106]

$\sf volume \ of \ cone = \dfrac{1}{3} \pi r^2h$ ** where "r" is radius and "h" is height **

$\sf volume \ of \ cylinder= \pi r^2h$

$\boxed{ \sf \tfrac{1}{3}}$ as it refers to the volume of cone being 1/3 of the the volume of cylinder

Hardest, example:

given height of cone is 69 km and radius is 48 km

using the formula:

$\hookrightarrow \sf volume \ of \ cone = \dfrac{1}{3} \pi (48)^2(69)$

$\hookrightarrow \sf volume \ of \ cone = 52992\pi$

$\hookrightarrow \sf volume \ of \ cone = 166479.3 \ km^3$

the area of a rectangular wall of a barn is 260 square feet. it's length is 6 feel longer than twice it's width. find the length

scoundrel [369]

L=2w+6
260=lw

Substitute for l
260=w(2w+6)
260= 2w^2+6w
2w^2+6w-260=0
2(w^2+3w-130)
2(w+13)(w-10)
w=-13, w=10

Since width cannot be negative it must be 10
260=l(10)
26=l

Final answer: length-26 ft, width-10ft
