4x - 3y = 51, when x = 15

Plug in 15 for x.

4(15) - 3y = 51

Simplify.

60 - 3y = 51

Subtract 60 from both sides.

-3y = 51 - 60

Simplify.

-3y = -9

Divide both sides by -3.

y = -9/-3

Simplify.

y = 3

Divide the following polynomial and then place the answer in the proper location on the grid. Write your answer in order of desc

irga5000 [103]

given,

$\frac{ {y}^{3} - {y}^{2} + y + 3}{y + 1} \\ = \frac{ {y}^{3} + {y}^{2} - 2 {y}^{2} - 2y + 3y + 3}{x + 1} \\ = \frac{{y}^{2} (y + 1) - 2y(y + 1) + 3(y + 1)}{(y + 1)} \\ = \frac{(y + 1)( {y}^{2} - 2y + 3) }{(y + 1)} \\ = {y}^{2} - 2y + 3$
