The solution will be where the lines intersect. That point satisfies both equations of the lines.

A = (3,5)

B = infinate - overlying lines have infinate points that solutions.

C = no solution - parallel lines never intersect

Help me hurry pls !Solve the following 4-(x-2)=2x-12+3x show the work please I dont understand ! Help

irina1246 [14]

Perform indicated multiplication on left side..

4-x+2=2x-12+3x combine like terms on both sides

-x+6=5x-12 subtract 5x from both sides

-6x+6=-12 subtract 6 from both sides

-6x=-18 divide both sides by -6

x=3

What is the third term in the binomial expansion of (3x y3)4? 54x2y3 18x2y3 18x2y6 54x2y6.

hjlf

From the simplified form of the expression, the third term on expansion is $54x^2y^6$

Given the expression $(3x + y^3)^4$

For binomial expansion, the power of 3x will be decreasing while y^3 will be increasing.

On expansion, the resulting expression will be:

$=(3x + y^3)^4\\=(3x)^4(y^3)^0 + 4 (3x)^3(y^3)^1 + 6(3x)^2(y^3)^2 + 4(3x)^1(y^3)^3 + (3x)^0(y^3)^4\\$

Simplify the result to have:

$=81x^4+81x^3y^3+54x^2y^6+12xy^9+y^{12}$

From the simplified form of the expression, the third term on expansion is $54x^2y^6$
