Let's plug 5 in for y.

$4(5)^{2} - 7(5) - 6\\\\\\\\4(25) - 35 - 6\\\\\\100 - 35 - 6 = 59$

Answer 2

Answer:

59

Step-by-step explanation:

You can just replace y with its value which is 5.

4y² - 7y - 6 = 4(5²) - 7(5) - 6

                  = 4 × 25 - 35 - 6

                  = 100 - 35 - 6

                  = 59
