30 points i will give brainliest to first correct answer which statements are true about the ordered pair (10, 5) and the system of equations? {2x−5y=−5x+2y=11 select each correct answer. the ordered pair (10, 5) is a solution to the first equation because it makes the first equation true. the ordered pair (10, 5) is a solution to the second equation because it makes the second equation true. the ordered pair (10, 5) is not a solution to the system because it makes at least one of the equations false. the ordered pair (10, 5) is a solution to the system because it makes both equations true.

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
