(1,3), (3,-2) 

m=(y2-y1) / (x2-x1) where (x1 = 1) (y1= 3) (x2=3) (y2=-2)
m=(-2-3)/(3-1)
m=-5/2

therefore slope = -5/2

Slope is rise over run or (y₁-y₂)/(x₁-x₂)

(x,y)
(1,3)
(3,-2)

(3-(-2))/(1-3)=(3+2)/(1-3)=5/-2

slope is -5/2

How to find the edge length in volume?
vlada-n [284]
So we can take the volume of a cube formula and set it equal to the volume that we actually know: 64 centimeters cubed. So in order to find the length of the edge, which is a side, we need to cube root both sides of this equation. On the left-hand side, the cube root cancels all the cube.

Factor 125x3 + 343y3
Annette [7]

Answer:

(5x + 7y)(25x² - 35xy + 49y²)

Step-by-step explanation:

125x³ + 343y³ ← is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b² )

125x³ = (5x)³ ⇒ a = 5x

343y³ = (7y)³ ⇒ b = 7y

125x³ + 343y³

= (5x + 7y)((5x)² - (5x × 7y) + (7y)²)

= (5x + 7y)(25x² - 35xy + 49y²) ← in factored form
