Which ordered pair is a solution of the equation? y=-3x-4 choose 1 (choice a) a only (-2,4) (choice b) b only (-3,5) (choice c) c both (-2,4) and (-3,5) (choice d) d neither

B.- Only (-3,5)

Step-by-step explanation:

In an ordered pair the first coordinate is the coordinate, and the second coordinate corresponds to the coordinate.

Then we must substitute the given value of in the equation and verify that we get in return the defined value for .

the options are

in this one , and , so let's confirm:

this is not a solution since the values are not the same.

in this one and , let's also confirm:

in this one the values for are equal, this is a solution for the equation.

idk do it yourself or ask somebody idk stop going online asking for

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
