Corrected Question

If f(x) = -3x+4 and g(x) = 2, solve for the value of x for  which f(x) = g(x) is true.

Step-by-step explanation:

Given the functions:

When f(x)=g(x), we have:

-3x+4=2

Collect like terms by subtracting 4 from both sides

-3x+4-4=2-4

-3x=-2

Divide both sides by -3 to solve for x.

We conclude therefore that at , the values of f(x) and g(x) are equal.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

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)
