Which linear inequality is represented by the graph? -6
Oys 2x + 4
Oys +x+ 3
5
4
o yz x+3
O y 2x + 3
Mark thi

B

Step-by-step explanation:

By the way the graph is shaded, the answer would have to be one of the first two, one of the "Y is less than and equal to ...".

If you look at the point at which the line intercepts with the Y-axis, it would be 3, which means the answer is the second option.

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)
