A line is given by the equation y=x+2. Determine which of the following points belong to this line: M(0, 2),N(1, 3), A(−1, 1), B(−4.7, −2.7), C(−2 1 2 , 1 2 ).

M,N,A,B

Step-by-step explanation:

all the points above satisfy the given eqn

eg, A(-1,1)

y=x+2,x=-1

y=-1+2

y=1 but C doesn't satisfy the eqn (-2 1/2,1/2)

y= -2 1/2 +2

y= -1/2

should you really be posting this isn't math boi.

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)

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