Answer:

<h2>3y + 2 = 8</h2>

Step-by-step explanation:

solve A

2y - 3 = 19

2y = 22

y = 11

solve B

3y + 2 = 8

3y = 6

<h2>y = 2</h2>

solve C

4y - 4 = -4

4y = 0

y = 0

solve D

5y + 1 = 10

5y = 9

y = 9/5

Answer:

The answer to your question is: Yes, x - 5  is a factor of the polynomial.

Step-by-step explanation:

To answer this question you need  to divide the polynomial by the factor and if there is nothing left, they are factor.

                   

                             <u>x³ -4x² -7x +10</u>

                                      x -5

                         

                         x²  + x -2

              x-5      x³ -4x² -7x +10

                        -x³ + 5x²

                               x²  - 7x

                             -x²   + 5x

                                      -2x + 10

                                      +2x -10

                                         0     0       These zeros tell us that the linear

                                                          expression is a factor of the polynomial
