Which of the following coordinate points is the point of intersection of these two lines?
y-6x=-4
y-2x=8

A. (12/8,11)
B. (3,14)
C. (9/6,5)
D. (-1/2,7)

The point of intersection of these two lines will be: (3, 14)

Step-by-step explanation:

Given the equations

Solving the system of the equations

Therefore, the point of intersection of these two lines will be: (3, 14)

600,000,000,000, or 6e14

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

mrb

(a + b) (a^2 - a b + b^2)
