y=

x = 11, y = 3

Step-by-step explanation:

9x + 25 and 13x - 19 are corresponding angles and congruent, thus

13x - 19 = 9x + 25 ( subtract 9x from both sides )

4x - 19 = 25 ( add 19 to both sides )

4x = 44 ( divide both sides by 4 )

x = 11

Thus

13x - 19 = (13 × 11) - 19 = 143 - 19 = 124°

13x- 19 and 17y + 5 form a straight angle and are supplementary, thus

13x - 19 + 17y + 5 = 180, that is

124 + 17y + 5 = 180

129 + 17y = 180 ( subtract 129 from both sides )

17y = 51 ( divide both sides by 17 )

y = 3

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
